5.4.1 Insulators and Conductors

Front

What is a conductor?

Back

A conductor is a material that allows electrical energy 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 electrical energy to flow through it easily. Examples include rubber, plastic, and wood.

Front

Which material is commonly used as an insulator for electrical wires?

Back

Rubber is commonly used as an insulator for electrical wires because it prevents electrical energy from escaping.

Front

What happens when a conductor is connected in a circuit?

Back

When a conductor is connected in a circuit, it allows electrical energy to flow, which can power devices like light bulbs.

Front

What is the purpose of insulation around electrical wires?

Back

The purpose of insulation around electrical wires is to prevent electrical energy from escaping and to protect people from electric shocks.

Front

Can you name a common conductor found in households?

Back

A common conductor found in households is copper, which is used in electrical wiring.

Front

What is the role of aluminum foil in a circuit?

Back

Aluminum foil acts as a conductor in a circuit, allowing electrical energy to flow and potentially making a light bulb glow.

Front

Why is rubber used in electrical appliances?

Back

Rubber is used in electrical appliances as an insulator to prevent electrical energy from escaping and to ensure safety.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electrical energy to flow easily, while insulators resist the flow of electrical energy.

Front

Give an example of a situation where an insulator is important.

Back

An insulator is important when covering electrical wires to prevent accidental shocks and ensure safety.
