The path through which electric current ows is called electric circuit.
Source, load and conducting wires are required to make an electric
circuit.

Cell, generator, dynamo, etc are sources, wire is a conducting wire
and the devices which use electricity are loads. Here, bulb is the load.
Switch is also kept in the electric circuit to break the circuit when the

device is not in use.

Open circuit and closed circuit

Open circuit

The circuit through which current

is not owing is called open circuit.
In open circuit, the switch is off
between the load and the source.

Closed circuit
The circuit through which current
is owing is called closed circuit. In

closed circuit, the switch is on.

Conductors and insulators

There are various types of substances around us. Some of them allow
current to pass through them whereas others do not.
