Electrical potential is measured in which of the following?

Ohms
Watts
Amperes
Volts

The correct answer is: Volts

Electrical potential is measured in volts. This unit represents the amount of electric potential energy per unit charge. Specifically, one volt is defined as the potential difference that would drive one ampere of current against one ohm of resistance. Understanding this relationship is crucial in fields like physics and engineering, as it helps in analyzing electrical circuits and systems. Other units, such as ohms, watts, and amperes, serve different purposes in the context of electricity. Ohms measure electrical resistance, which is the opposition to current flow. Watts quantify power, indicating how much energy is being used or generated per unit time. Amperes, on the other hand, measure current—the flow of electric charge in a circuit. Each of these units plays a vital role in understanding electrical concepts, but only volts pertain specifically to electrical potential.
