Electricity and Circuits Quiz

What is a circuit?

• A type of battery

• A route through which electrical current can flow

• A type of wire

• A type of light bulb

Where do electrons flow from in a D-cell battery?

• Negative side

• Positive side

• Metal base

• Filament

What happens to the electrical energy when electrons go through the filament of a light bulb?
