Which unit correctly identifies the unit expressing electrical potential?

Which unit correctly identifies the unit expressing electrical potential?

• A. Amps
• B. Ohms
• C. Volts
• D. Watts

Answer: (C)

Electrical potential, or voltage, is the push that drives electric charges through a circuit, and its unit is the volt. It represents the potential difference between two points and tells you how much energy per unit charge is available to move charges. This is distinct from current, which is measured in amps and reflects how much charge is actually flowing; resistance, measured in ohms, describes how much a component resists that flow; and power, measured in watts, is the rate at which energy is transferred (volts times amps). So the unit that expresses electrical potential is volts.
