Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow through it easily (e.g., metal), while an insulator does not allow electricity to flow (e.g., rubber).

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an open circuit?

Back

An open circuit is a broken loop that prevents current from flowing.

Front

What is a series circuit?

Back

A series circuit is a circuit where components are connected one after another, so there is only one path for current to flow.

Front

What is a parallel circuit?

Back

A parallel circuit is a circuit where components are connected across common points, allowing multiple paths for current to flow.

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

Back

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

Front

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

Back

If one bulb burns out in a parallel circuit, the other bulbs remain lit.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy.
