Front

What is the role of an insulator in an electric circuit?

Back

An insulator prevents the flow of electricity, protecting components and users.

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electricity to flow from a power source to a device and back.

Front

How does increasing the number of coils in an electromagnet affect its strength?

Back

Increasing the number of coils increases the strength of the electromagnet.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow easily, while an insulator resists the flow of electricity.

Front

What is the function of a fuse in an electric circuit?

Back

A fuse protects the circuit by breaking the connection if the current is too high.
