Unit 08: Electricity Practice

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that prevents electricity or heat from flowing through it. Examples include rubber, glass, and plastic.

Front

What happens when electricity flows through a conductor?

Back

When electricity flows through a conductor, it can create a magnetic field around it.

Front

What is the role of a circuit in electricity?

Back

A circuit is a closed loop that allows electricity to flow. It must be complete for devices like lightbulbs to work.

Front

Why is copper commonly used in electrical wiring?

Back

Copper is a good conductor of electricity, meaning it allows electricity to flow easily, making it ideal for wiring.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily, while insulators do not allow electricity to flow.

Front

What is an example of a good insulator?

Back

Glass is a good insulator because it does not allow electricity to flow through it.

Front

What can happen if an insulator is damaged?

Back

If an insulator is damaged, it may allow electricity to flow where it shouldn't, which can be dangerous.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction.

Front

How does a lightbulb work in a circuit?

Back

A lightbulb works by allowing electricity to flow through a filament, which heats up and produces light.
