Front

What is the role of conductors in electrical circuits?

Back

Conductors allow electric current to flow through the circuit, enabling devices to work.

Front

What is the role of insulators in electrical circuits?

Back

Insulators prevent the flow of electricity, protecting users from electric shock and ensuring that electricity flows only where it is intended.

Can you name a common insulator found in homes?

Back

A common insulator found in homes is the plastic covering on electrical wires.

Front

What happens when a conductor is connected to a power source?

Back

When a conductor is connected to a power source, it allows electricity to flow through it, powering devices.

Front

What happens when an insulator is connected to a power source?

Back

When an insulator is connected to a power source, it prevents electricity from flowing, keeping devices safe.
