Which of the following units is used to measure electrical power?

The unit used to measure electrical power is the Watt. This unit quantifies the rate at which electrical energy is converted or transferred. In practical terms, one Watt is defined as one Joule per second, which means it describes how much energy is used or generated over a period.

In electrical circuits, power can be calculated using the formula P = IV, where P is power in Watts, I is current in amperes, and V is voltage in volts. This relationship highlights how Watts are directly linked to both current and voltage in electrical systems.

Joules measure energy, not power, as they represent the total energy utilized or transferred. Ohms are the units of resistance in an electrical circuit, defining how much the flow of electric current is opposed. Farads are units of capacitance, which measure a capacitor's ability to store an electrical charge. Thus, understanding that power is specifically measured in Watts clarifies its distinct role in electrical engineering and related fields.
