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.This pictorial diagram shows us a physical connection that is much easier to understand in an electrical circuit or system. An electrical diagram can indicate all the interconnections, indicating their relative positions. The use of this Array can be positively recognized in a production project or in solving electrical problems.

This can prevent a lot of damage that even derail electrical plans. The layout facilitates communication between electrical engineers designing electrical circuits and implementing them. The pictures are also helpful in making repairs. It shows whether the installation has been appropriately designed and implemented while confirming the safety regulators. A usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device.

This is unlike a schematic diagram, where the arrangement of the components interconnections on the diagram usually does not correspond to the components physical locations in the finished device.

A pictorial would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance. Basic Electrical Circuit Diagram show the circuit flow with its impression rather than a genuine representation.

They only provide general information and cannot be used to repair or examine a circuit. The functions of different equipment used within the circuit get presented with the help of a schematic diagram whose symbols generally include vertical and horizontal lines.

However, these lines are known to show the flow of the system rather than its wires. A represents the original and physical layout of electrical interconnections. Wiring on the picture with different symbols shows the exact location of equipment in the whole circuit. Its components are shown by the pictorial to be easily identifiable. They are often photos attached with highly-detailed drawings or labels of the physical components.

A person with a strong knowledge of electrical wiring diagrams can only understand a pictorial. What is a simple electrical circuit? Circuit diagram - WikipediaWikipedia. FRDiagram Database - Lovecon.

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. 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?Ongoing donations help keep the site running.

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.

Varsity font google

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.

John proctor

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.

BAT1 and L1 as shown in the circuit below. A second light bulb in the circuit would then have the reference designator L2. Circuit diagrams or schematic diagrams show electrical connections of wires or conductors by using a node as shown in the image below. A node is simply a filled circle or dot. When three or more lines touch each other or cross each other and a node is placed at the intersection, this represents the lines or wires being electrically connected at that point.

Wiring Diagram

If wires or lines cross each other and there is no node, as shown at the bottom of the above image, the wires are not electrically connected. In this case the wires are crossing each other without connecting, like two insulated wires placed one on top of the other.

In the circuit below, two light bulbs are connected in parallel to a battery power source. It can be seen that the top terminals of the two light bulbs are connected together and to the positive terminal of the battery. We know this because the three terminals or connection points have a node where they intersect. The bottom terminals of the bulbs are connected to each other and to the negative terminal of the battery, because the second node shows these connections.
