Learn to read electrical and electronic circuit diagrams or schematics.
A drawing of an electrical or electronic circuit is known as a circuit diagram, but can also be called a schematic diagram, or just schematic. Circuit or schematic diagrams consist of symbols representing physical components and lines representing wires or electrical conductors.
In order to learn how to read a circuit diagram, it is necessary to learn what the schematic symbol of a component looks like. It is also necessary to understand how the components are connected together in the circuit. Probably the simplest circuit that can be drawn is one that you may have seen in a school science class: a battery connected to a light bulb as shown below.
Each electronic or electrical component is represented by a symbol as can be seen in this simple circuit diagram. Lines used to connect the symbols represent conductors or wires. Each symbol represents a physical component that may look as follows. The physical circuit for the above circuit diagram may look something like the image below, although a more practical physical circuit would have a light bulb holder and clamps that connect to the battery terminals.
A light bulb holder would have screw terminals to connect the wires to, and a socket to screw the light bulb into. Battery clamps would allow the wires to easily be connected between the battery and light bulb holder. Typically the actual battery type and bulb type would be specified in a component list that accompanies the circuit diagram. More information on the bulb and battery type could also be included in the circuit as text.
For example, the battery may be specified as a The light bulb may be specified as a 12V 5W incandescent bulb, or 9V 0. Components in a circuit should always have references, also called reference designatorsused to identify the components in the circuit.
This allows the components to easily be referenced in text or a component list. A battery may have the reference designator "BAT" and a light bulb may have a reference "L".
Because there could be more than one battery or light bulb in a circuit, reference designators will usually always end with a number, e.These days almost everybody uses electricity in their houses and work places. So having at least a basic understanding of domestic electric circuits would help you immensely. I thought to help you achieve that goal through this post.
It is important to have a basic knowledge of these parts to make your life easier when it comes to using electricity the hassle-free way. In countries such as Sri Lanka, India, Nigeria and many others have v basic electricity power supply to consumers from the national electricity grid which is an alternating current AC with a 50Hz frequency. However, the Voltage and Frequency can be different for other countries, for example United States has v electric power supply with a 60Hz frequency. First in the list of common electrical parts you see everyday is the Electric meter.
It is used by the national electricity grid to measure the units of electrical energy used in your household circuits. Suppose you have a W electrical appliance in your house and you have to use this appliance for one hour everyday. Then the electrical energy consumed is one kilowatt-hour per day. Electric Meter calculate this consumed electric energy through the circular disc fixed in it.
When you use electricity, this circular disc starts to rotate which records the number of electrical energy units used by you. If you look closer inside the meter, you can see there are digits moving at the same time when the circular disc rotates. Electricity grid company uses that meter readings to create your monthly electricity bill every 30 days or so. Basically fuses are used to protect electrical appliances, parts and electronic components from potential damage due to a high current — Ampere — flowing in the circuit.
This electrical part is a small length thin wire created using lead and tin alloy. These days fuse wire is commonly seen in a glass tube for easy use. There are different fuse wires with the ability to conduct certain maximum currents such as 3A, 5A, 13A and 15A. When designing the circuit diagram the circuit designers use various symbols. Do you know which symbol represents a fuse?
Curious on how exactly a simple wire do the protection duty without the muscles? When electrical current flows through the circuit exceeding the rated ampere value of the fuse, the thin wire melts down fuses thanks to heating effect of electric current and in return makes the closed-circuit an open-circuit. In other words, fuse is kind of a superhero which saves the day by sacrificing itself for the greater good.
This is why when the fuse goes down, you need to replace same value and same size of fuse. This is also a safety rule.
Want to know more electrical safety rules? Since replacing fuses seem annoying, a new electrical part was created to avoid such complications. This component is a miniature circuit breaker and it looks like a switch consisting various ampere values. Circuit breakers function similar to fuses. In the event of an exceeding current flow than the rated ampere value, the switch opens and stops the current, instead of melting anything or dying forever.
The circuit can be connected again by closing the switch. Distribution box is another easy to notice electrical part in your home. It consists 3 more electrical partsnamely. As the name implies, Distribution Box simply distributes the electric supply to sections of the house.
In each of these circuits the Live Wire is connected to a circuit breaker which will be explained in a moment. You know every house or commercial building has a distribution box which is where the Main Switch is located.Test your basic knowledge. Subject : engineering.

Wiring Diagrams, Device Locations and Circuit Planning A typical set of house plans shows the electrical symbols that have been located on the floor plan but do not provide any wiring details. It is up to the electrician to examine the total electrical requirements of the home especially where specific devices are to be located in each area and then decide how to plan the circuits.
The installation of the electrical wiring will depend on the type of structure and construction methods being used. For example, a stick frame home consisting of standard wood framing will be wired differently than a SIP or Structured Insulated Panel home because of access restrictions. This electrical wiring project is a two story home with a split electrical service which gives the owner the ability to install a private electrical utility meter and charge a renter for their electrical usage.

Diagram Database. Basic Electrical Motor Control Circuit Wiring Diagrams are already applied since historical occasions, but turned far more common through the Enlightenment. Overview The phrase "Basic Electrical Motor Control Circuit Wiring Diagram" in its frequently utilised sense can have a basic or precise this means: visual info unit : Much like the term "illustration", "Basic Electrical Motor Control Circuit Wiring Diagram" is applied to be a collective phrase standing for The full course of complex genres, which includes graphs, technological drawings and tables.
In science the phrase is Employed in both of those ways. By way of example, Anderson said a lot more typically: "Basic Electrical Motor Control Circuit Wiring Diagrams are pictorial, yet summary, representations of data, and maps, line graphs, bar charts, engineering blueprints, and architects' sketches are all examples of Basic Electrical Motor Control Circuit Wiring Diagrams, whereas photographs and video clip aren't".
Or in Hall's words "Basic Electrical Motor Control Circuit Wiring Diagrams are simplified figures, caricatures in a way, intended to convey crucial meaning". The fundamental form according to White may be characterized with regard to "class, clarity, simplicity, sample, simplicity, and validity".
Some a lot more examples abide by. SDL is a formal language used in computer science. Other Files.So, how to read car wiring diagrams? A car wiring diagram is a map. To read it, identify the circuit in question and starting at its power source, follow it to ground.
Use the legend to understand what each symbol on the circuit means. A wiring circuit is so called because the wiring must make a complete circle, any break in this circle, causes a fault. Power leaves the positive side of the car battery through the power cables and is always actively looking for the shortest possible return path to the negative side of the car battery. Power is battery voltage and in any circuit the path to the load from battery positive may be described as the power side of the circuit.
As you know, voltage loves to travel through any metal, and not just the metal within wires. The return path after the load is known as the ground side of a circuit.
The function of a relay is to control a high amp circuit like a starter motor or head lights using a low amp switch circuit. Running high amps through a small switch would cause the switch to burn out and fail, possibly starting a fire.
Relays are common in circuits and also housed within control units. A relay is a electromagnetic switch, it has two separate circuits, a Control circuit and a Load circuit. This causes the coil of the relay to become magnetic, which pulls the movable armature within the relay, closed. When closed open in the above diagramit allows power travel from the battery to the light. Through the 30 and 87 pins. When the switch is turned off, battery disconnected the coil is no longer magnetic and the spring loaded movable armature returns to open default position.
The starter circuit relay in the pic above operates in an identical fashion.
Electrical Wiring Diagram and Electrical Circuit Diagram Difference
By turning the ignition switch to start, voltage flows through pin 86 and grounds at This magnetises the coil which in turn causes the armature pin 30 to 87 to close completing the load side circuit, and the engine cranks. Modern cars as you know are packed with control modules.
Pre-computer classic cars have a simple wiring circuit — for example, pressing a switch sends power through a wire, to a window motor and the window moves. Modern cars handle it a little differently — pressing a switch, sends a signal through a wire to a control unit computerwhich in turn sends power to the window motor. The control unit or controller will only send power to the window motor if certain pre-programmed conditions are met.
Of course the window may not move for other reasons, the control unit may be faulty, or software needs to be updated or re-flashed, motor faulty etc. So why did they go and make things more complicated and expensive to fix?A wiring diagram is a simple visual representation of the physical connections and physical layout of an electrical system or circuit. It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system.
Use wiring diagrams to assist in building or manufacturing the circuit or electronic device. They are also useful for making repairs. For example, a home builder will want to confirm the physical location of electrical outlets and light fixtures using a wiring diagram to avoid costly mistakes and building code violations.
SmartDraw comes with pre-made wiring diagram templates. Customize hundreds of electrical symbols and quickly drop them into your wiring diagram. Special control handles around each symbol allow you to quickly resize or rotate them as necessary. To draw a wire, simply click on the Draw Lines option on the left hand side of the drawing area. If you right click on a line, you can change the line's color or thickness and add or remove arrowheads as necessary.
Drag a symbol onto the line and it will insert itself and snap into place. Once connected, it will remain connected even if you move the wire. If you need additional symbols, click the arrow next to the visible library to bring up a drop down menu and select More.
You'll be able to search for additional symbols and open any relevant libraries. You can also change the size and shape of your line hops. Select Show Dimensions to show the length of your wires or size of your component. Click here to read SmartDraw's complete tutorial on how to draw circuit diagrams and other electrical diagrams. A schematic shows the plan and function for an electrical circuit, but is not concerned with the physical layout of the wires.
Wiring diagrams show how the wires are connected and where they should located in the actual device, as well as the physical connections between all the components. Unlike a pictorial diagram, a wiring diagram uses abstract or simplified shapes and lines to show components.
Pictorial diagrams are often photos with labels or highly-detailed drawings of the physical components. If a line touching another line has a black dot, it means the lines are connected.
When unconnected lines are shown crossing, you'll see a line hop. Most symbols used on a wiring diagram look like abstract versions of the real objects they represent. For example, a switch will be a break in the line with a line at an angle to the wire, much like a light switch you can flip on and off. A resistor will be represented with a series of squiggles symbolizing the restriction of current flow. An antenna is a straight line with three small lines branching off at its end, much like a real antenna.
