Circuits

Front

What is a circuit?

Back

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

Front

What is needed to create a complete circuit?

Back

A complete circuit requires a power source (like a battery), conductive materials (like wires), and a load (like a light bulb).

Front

What happens if a circuit is incomplete?

Back

If a circuit is incomplete, the electric current cannot flow, and devices like light bulbs will not work.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What materials can conduct electricity?

Back

Materials that can conduct electricity include metals like copper, aluminum, and silver.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy.

Front

What does it mean for a light bulb to be part of a complete circuit?

Back

For a light bulb to work, it must be connected in a complete circuit, allowing electric current to flow through it.

Front

What is the function of wires in a circuit?

Back

Wires connect different components of a circuit and allow electric current to flow between them.

Front

What can cause a light bulb to not light up?

Back

A light bulb may not light up if it is broken, if the circuit is incomplete, or if the battery is dead.

Front

What is the purpose of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit.
