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

Back

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

Front

What happens to the light bulbs in a series circuit if one bulb burns out?

Back

All bulbs will go out because the circuit is broken.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

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

Back

A switch controls the flow of electricity by opening or closing the circuit.

Front

Why is copper commonly used for electrical wiring?

Back

Copper is a good conductor of electricity, allowing for efficient current flow.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, preventing current from flowing.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow.

Front

How does adding more light bulbs in series affect the brightness of each bulb?

Back

Adding more light bulbs in series decreases the brightness of each bulb due to increased resistance.

Front

What is the function of a resistor in a circuit?

Back

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

Front

What is the effect of closing a switch in a circuit with multiple components?

Back

Closing a switch allows current to flow, potentially lighting bulbs or powering devices.
