What is a circuit?

Back

A circuit is a closed path through which electricity flows.

Front

What happens when a switch is open in a circuit?

Back

When a switch is open, the circuit is incomplete, and electricity cannot flow, so devices like light bulbs will not work.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or plastic.

Back

Electricians wear rubber gloves to protect themselves from electric shocks, as rubber is an insulator.

Front

What happens if one bulb in a series circuit burns out?

Back

If one bulb in a series circuit burns out, the entire circuit is broken, and all bulbs will go out.

Front

What happens if one bulb in a parallel circuit burns out?

Back

If one bulb in a parallel circuit burns out, the other bulbs will continue to light up.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is a switch?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is the purpose of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy.
