Electrical Circuit

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

• It increases the strength of the electricity.

• It changes electricity to light energy.

• It provides electricity to the battery.

• It opens and closes the circuit.

Resistance is a measure of...

• the number of terminals

• how hard it is for electrons to move through the battery

• how hard it is for electrons to move through the circuit

• how many volts are in the battery

Why is electrical wiring usually made from copper?

• Because copper is shiny

• Because copper conducts electricity

• Because copper is not magnetic

• Because copper insulate electricity

• open

• closed

Is this an open circuit or closed circuit?

• open

• closed

Which type of circuit is Circuit A?

• series

• parallel

• perpendicular

Why did the person who made Circuit A probably connect the wires to a penny?

• They needed to use a penny to make the bulb light.

• They were testing to see if the penny conducts electricity.

• The penny will prevent sparks.
