What is an electrical circuit?

An electrical circuit is a path or line through which an electrical current flows. The path may be closed (joined at both ends), making it a loop. A closed circuit makes electrical current flow possible. It may also be an open circuit where the electron flow is cut short because the path is broken. An open circuit does not allow electrical current to flow.

Below is a basic set of symbols that you may find on circuit diagrams.
electrical circuit symbols

It is very important to know the basic parts of a simple circuit and the symbols that relate to them. A simple circuit has conductors, a switch, a load and a power source. Here are the functions of each part:

parts of an electrcial circuitConductors:
These are usually copper wires with no insulation. They make the path through which the electricity flows. One piece of the wire connects the current from the power source (cell) to the load. The other piece connects the load back to the power source.

parts of an electrcial circuitSwitch:
The switch is simply a small gap in the conductor where you can close or open the circuit. When the switch is closed, the circuit is closed and electricity flows.

parts of an electrcial circuitThe Load:
The load is a small light bulb or buzzer that lights when the circuit is turned on. The load is also known as a resistor.

parts of an electrcial circuitCell:
The power source is a cell. (Note that more than one cell put together is known as a battery)

The diagram below shows how a basic circuit looks like.

It is important to draw circuits with clean straight lines, as shown in diagram B. Avoid realistic sketches. It is important to know that a circuit can have more than the basic components in the diagram. It can have two or more batteries or two or more bulbs.

There are two types of circuits namely Series Circuit and Parallel Circuit. Click on each to learn more.
