Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electric current to flow easily (e.g., metals), while an insulator resists the flow of electric current (e.g., rubber, wood).

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing multiple paths for current to flow.

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 happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing current to flow and powering the connected devices.

Front

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

Back

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

Front

What is an example of a good conductor?

Back

Copper is a good conductor of electricity.

Front

What is an example of a good insulator?

Back

Rubber is a good insulator and is often used to cover electrical wires.

Front

What is the effect of adding more light bulbs in a series circuit?

Back

Adding more light bulbs in a series circuit increases the total resistance, which can make the bulbs dimmer.
