Circuits and Electricity

Front

What is a circuit?

Back

A circuit is a closed path through which electricity flows.

Front

What are the two main types of circuits?

Back

The two main types of circuits are series and parallel.

Front

What happens when a switch is closed in a circuit?

Back

When a switch is closed, the circuit is complete, and electricity can flow, turning on the light.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily.

Front

Why do electricians wear rubber gloves?

Back

Electricians wear rubber gloves because rubber is an insulator, protecting them from electric shock.

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

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

Back

If one light bulb burns out in a series circuit, all the lights go out because the circuit is broken.

Front

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

Back

If one light bulb burns out in a parallel circuit, the other lights remain on because they have separate paths for electricity.

Front

What is the role of a battery in a circuit?

Back

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