Why do electrical circuits have to be closed?

• so that the electrons stay in the battery

• so that the resistance is higher

• so that the heat doesn't escape

• so that the electrons can flow without interruption

Which of the following is NOT required for an effective electrical circuit?

• device that uses electricity

• voltage source

• conductor
• switch

_____ pushes the electricity through a circuit

• resistance
• voltage
• current
• switch

Why must every electric circuit have a voltage source, such as a battery?

• Without a voltage source, the resistance would be too high

• Without a voltage source, the resistance would be too low

• Without a voltage source, there would be no electrons in the circuit

• Without a voltage source, there would be nothing to push electrons

The flow of electricity through a conductor is called...

• resistance
• voltage
• current
• source of electric current

The positive and negative terminal of a battery represent...

• where protons and electrons build up in a circuit

• the high and low electric potential established by a battery

• the location were electrons are created and recycled

• none of these
