Question 1

What is the source of electricity in an electric torch?

Accepted Answer

An electric torch uses an electric cell as the source of electricity. The cell provides the necessary electric current to make the bulb glow when the switch is turned on.

Question 2

How many terminals does an electric cell have?

Accepted Answer

An electric cell has two terminals: a positive terminal and a negative terminal. These terminals are used to connect the cell in a circuit.

Question 3

Which part of an electric bulb glows when current passes through it?

Accepted Answer

The filament of an electric bulb glows when electric current passes through it. The filament is made of a thin wire that becomes very hot and emits light.

Question 4

What is a closed electric circuit?

Accepted Answer

A closed electric circuit is an unbroken path that allows electric current to flow from one terminal of the cell to the other, making the device (like a bulb) work.

Question 5

Materials that allow electricity to pass through them are called:

Accepted Answer

Materials that allow electric current to pass through them easily are called conductors of electricity, such as metals like copper, aluminum, and iron.
