What is the basic unit of measurement for electrical power?

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

Answer: (B)

The basic unit of measurement for electrical power is the watt. Power is defined as the rate at which electrical energy is transferred by an electric circuit, and it is calculated by the product of voltage (volts) and current (amperes). Therefore, one watt is equivalent to one volt multiplied by one ampere, making watts the correct unit to express electrical power. Volts measure electrical potential difference, amperes measure the flow of electric current, and ohms measure resistance in a circuit. While all these units are crucial in understanding electrical systems, they serve different purposes in electrical calculations and do not directly represent power itself. The watt is the specific measurement that quantifies how much energy is being used or produced over time, which is why it stands as the fundamental unit for electrical power.
