Front

What is a circuit?

Back

A circuit is a closed path through which electricity flows.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow and power devices like light bulbs.

Front

What is an open circuit?

Back

An open circuit is a broken path that prevents electricity from flowing, causing devices to not work.

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as wood or plastic.

Front

What happens when a switch in a circuit is open?

Back

When a switch is open, the circuit is incomplete, and electricity cannot flow, so devices like light bulbs will not work.

Front

What happens when a switch in a circuit is closed?

Back

When a switch is closed, the circuit is complete, allowing electricity to flow and power devices.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is the purpose of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when electricity flows through it.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across common points.
