Electric Circuits

Front

What makes up an electric circuit?

Back

An electric circuit is made up of a bulb, a battery, and wires.

Front

What is the role of a battery in an electric circuit?

Back

The battery serves as a source of energy for the circuit.

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

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

Front

What happens if a circuit is incomplete?

Back

If a circuit is incomplete, electricity cannot flow, and the bulb will not light up.

Front

What is the purpose of a switch in an electric circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

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 the same voltage source.

Front

How does the brightness of a bulb change in a series circuit?

Back

In a series circuit, if more bulbs are added, the brightness of each bulb decreases.

Front

How does the brightness of a bulb change in a parallel circuit?

Back

In a parallel circuit, each bulb receives the same voltage, so adding more bulbs does not affect their brightness.

Front

What is voltage?

Back

Voltage is the measure of electric potential energy per unit charge.
