• A device that stores electrical energy.

Which unit is used to measure electric potential or electromotive force?

• Volt

• Ampere

• Ohm

• Farad

What does voltage refer to in an electrical circuit?

• The potential difference between two points that drives current through a circuit.

• The flow of electric charge measured in amperes.

• The resistance to current flow.

• The amount of energy stored in a capacitor.

Which phenomenon is described as a natural discharge of static electricity, usually between clouds or from cloud to ground?

• Lightning
