What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an open circuit?

Back

An open circuit is a broken loop where current cannot flow.

Front

What is a series circuit?

Back

In a series circuit, all components are connected in a single path, so the same current flows through all of them.

Front

What is a parallel circuit?

Back

In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily.

Front

Why is rubber used as an insulator?

Back

Rubber is used as an insulator because it prevents electric current from passing through, protecting users from electric shock.

Front

What happens when a switch in a circuit is closed?

Back

When a switch is closed, it completes the circuit, allowing current to flow and devices like light bulbs to turn on.

Front

What happens when a switch in a circuit is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of current and turning off devices.
