Conductors, Insulators, and Circuits

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, plastic, and wood.

Front

What is a circuit?

Back

A circuit is a complete path that electricity can flow along. It includes a power source, wires, and a load.

Front

What is a power source?

Back

A power source provides the energy needed for a circuit to work. Examples include batteries and wall outlets.

Front

What is a load in a circuit?

Back

A load is a device that uses electricity to work, such as a light bulb or a fan.

Front

What happens when a circuit is open?

Back

When a circuit is open, electricity cannot flow, and the devices in the circuit will not work.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity can flow, and the devices in the circuit will work.

Front

Which material is the best conductor of electricity?

Back

Metals, especially copper and silver, are the best conductors of electricity.

Front

Which material is a good insulator?

Back

Rubber is a good insulator and is often used to cover electrical wires.

Front

What is the role of wires in a circuit?

Back

Wires connect different components of a circuit and allow electricity to flow between them.
