Front

What happens to the brightness of bulbs in a parallel circuit when more bulbs are added?

Back

The brightness stays the same for each bulb.

Front

What is needed to complete an incomplete electric circuit?

Back

A battery is needed to complete the circuit.

Front

If one bulb goes out in a parallel circuit, what happens to the other bulbs?

Back

The other bulbs will stay on.

Front

What materials can conduct electricity?

Back

Conductors include metals like copper, aluminum, and items like paper clips and pennies.

Front

What is a conductor?

Back

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

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a load.

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

What happens to the current in a series circuit if one component fails?

Back

The current stops flowing, and all components go out.

Front

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

Back

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