Insulators and Conductors

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to pass through easily. Examples include rubber and wood.

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to pass through easily. Examples include metals like copper and aluminum.

Front

What happens when you close a circuit?

Back

Closing a circuit allows electricity to flow, making devices like bulbs light up.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected in a single path, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected across common points, allowing multiple paths for current to flow.

Front

Give an example of a good conductor.

Back

Metal is a good conductor. For example, copper is often used in electrical wiring.

Front

Give an example of a good insulator.

Back

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

Front

What does it mean if a material is a poor conductor?

Back

A poor conductor means that the material does not allow electricity or heat to pass through easily.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What happens in an open circuit?

Back

In an open circuit, the path for electricity is broken, so electricity cannot flow and devices do not work.
