What is the typical unit for measuring electrical power?

• A. Joule
• B. Watt
• C. Ohm
• D. Ampere

Answer: (B)

The typical unit for measuring electrical power is the Watt. Power in electrical terms refers to the rate at which energy is used or generated. The definition of one Watt is one joule per second, which indicates the conversion of energy over a given period. This makes the Watt a key measurement in a variety of electrical applications, including calculations involving electrical devices and systems. Other units mentioned—like the Joule, Ohm, and Ampere—are related to electricity but serve different purposes. The Joule measures energy, the Ohm measures resistance, and the Ampere measures the flow of electric current. While all of these units are significant in the field of electrical engineering, the Watt specifically relates to power, solidifying its role as the conventional unit for this measurement in both practical and theoretical contexts.
