What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as 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, such as rubber, wood, or glass.

Front

Why does a light bulb glow when connected to a conductor?

Back

The light bulb glows because the electric current flows through the conductor, providing energy to the bulb.

Front

What happens if there is a break in a circuit?

Back

If there is a break in a circuit, the flow of electricity stops, and devices like light bulbs will not work.

Front

Can all materials conduct electricity?

Back

No, not all materials can conduct electricity. Only conductors allow electricity to flow.

Front

What is the main material found inside most electric wires?

Back

Copper is the main material found inside most electric wires because it is a good conductor.

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically carried by moving electrons in a conductor.
