Electric Circuits - Definition and basic concept of electrical circuits

What is an Electric Circuit?

In this article you will learn about Electrical Circuits in simple language with definition and easy concept.

Definition 

An Electric Circuit is a path in which electrons from a voltage or current source flow. 

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.

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. 

Parts of an Electrical Circuit

Conductors:

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.

Switch:

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.

The 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.

Cell:

The power source is a cell.
