If the power between two points of a conductor is one watt and the current is one amp, the potential difference between those points is what?

Explanation:
Power is the product of voltage and current, so voltage equals power divided by current. With 1 watt and 1 ampere, the calculation is 1 W ÷ 1 A = 1 volt. A volt is the unit for potential difference, which is exactly what’s being asked. The ampere is the unit of current, the watt is the unit of power, and the ohm is the unit of resistance, so they don’t describe the required quantity. Therefore, the potential difference between those points is 1 volt.
