Back

An electric circuit is a closed loop that allows electric current to flow through it.

Front

What is the main function of an electric circuit?

Back

To allow current to flow.

Front

What is electric current?

Back

Electric current is the flow of charged particles, typically electrons, through a conductor.

Front

What happens to charged particles when a battery is connected to a circuit?

Back

They flow from negative to positive.

Front

What is resistance in an electric circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current.

Front

What happens to electric current when it flows through a conductor?

Back

It flows easily.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily, such as rubber or glass.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is the direction of current flow in a circuit?

Back

Current flows from the positive terminal to the negative terminal of a battery.
