Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows energy, such as electricity or heat, to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow energy to flow through easily.

Rubber is a common insulator used to coat electrical wires.

Front

What is the role of conductors in an electrical circuit?

Back

Conductors allow electric current to flow through the circuit, enabling it to function.

Front

What is the role of insulators in an electrical circuit?

Back

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

Front

Which material is a better conductor: aluminum or glass?

Back

Aluminum is a better conductor than glass.

Front

What happens to the flow of electricity in a circuit with only insulators?

Back

The flow of electricity will be blocked, and the circuit will not work.

Front

What is the significance of using insulators in electrical devices?

Back

Insulators are crucial for safety, preventing accidental electric shocks and short circuits.

Front

How does temperature affect the conductivity of materials?

Back

Generally, as temperature increases, the conductivity of conductors increases, while the conductivity of insulators decreases.
