Electrical power is measured in which of the following units?

• A. Joules
• B. Amperes
• C. Volts
• D. Watts

Answer: (D)

Electrical power is measured in Watts, which is defined as the amount of energy transferred or converted per unit time. In the context of electrical systems, one Watt is equivalent to one Joule per second. Power is calculated using the formula P = IV, where P is power in Watts, I is current in Amperes, and V is voltage in Volts. This basic relationship highlights the interconnectivity of these units, with Watts representing the rate at which electrical energy is used or produced. Joules measure energy rather than power, as they quantify the total amount of work done or energy consumed. Amperes measure electrical current, which represents the flow of electric charge, while Volts measure the electrical potential difference. Although all these terms are related to electricity, it is Watts that specifically denotes power, making it the correct answer.
