Energy + Circuits

Front

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electricity to flow through it, powering devices like light bulbs.

Front

What happens in a series circuit when one bulb goes out?

Back

In a series circuit, if one bulb goes out, all bulbs will go out because the circuit is broken.

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.

Front

What is the role of wires in a circuit?

Back

Wires conduct electricity from one component to another, connecting the power source to devices.

Front

What happens if you replace a conductor with an insulator in a circuit?

Back

If you replace a conductor (like a metal paper clip) with an insulator (like a plastic spoon), the circuit will break and the bulb will not light.

Front

What is the difference between sound energy and light energy?

Back

Sound energy is produced by vibrating objects and travels in waves, while light energy is produced by sources like bulbs and travels in rays.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for electricity to flow, so if one path is broken, others can still work.

Front

What is a battery?

Back

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

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light energy when electricity passes through it.

Front

What is a switch?

Back

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