The safety device based on the heating effect of electric current is called a fuse.Fuse is a safety device, which limits current in circuit and breaks the circuit if the current exceeds its maximum limit

When current is switched ‘on’ in a room heater, it produces heat.Working of a room heater is based on the phenomenon of heating effect of electric current.

The combination of two or more cells is called a battery. To make a battery, the negative terminal of one cell is connected to the positive terminal of the next cell and so on.

Longer line in the symbol for cell representsits positive terminal.

Our body is a good conductor of electricity.

The core of an electromagnet is made from Iron.

When current is switched 'on' in a room heater, it gives out heat.

Circuit diagram is a simplified conventional pictorial representation of an electrical circuit.

The combination of two or more cells is called a Battery.

In an electric circuit, a fuse is a safety, device to prevent possible fire.
