Conductors vs. Insulators/Circuits

Front

What is a conductor?

Back

A material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily, such as rubber or glass.

Front

What is a semiconductor?

Back

Materials that can conduct electricity better than insulators but not as well as conductors, commonly used in electronic devices.

Front

What type of energy do batteries convert into electricity?

Back

Chemical energy.

Front

What is an electrical circuit?

Back

A closed path where electricity flows.

Front

What happens if a circuit is incomplete?

Back

Electricity cannot flow, and devices like light bulbs will not work.

Front

What is the role of a switch in a circuit?

Back

To open or close the circuit, allowing or stopping the flow of electricity.

Front

What is the function of a battery in a circuit?

Back

To provide the electrical energy needed to power devices.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, all components are connected in a single path; in a parallel circuit, components are connected across common points, allowing multiple paths for electricity.

Front

What is resistance in an electrical circuit?

Back

The opposition to the flow of electric current, measured in ohms.
