CFISD Electrical Circuits

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.

In the diagram below, describe the energy transformations that occur in the circuit, starting with the battery, when the light is on.
