What is the unit for measuring electrical power?

  1. Volts

  2. Amperes

  3. Watts

  4. Ohms

The correct answer is: Watts

The unit for measuring electrical power is Watts. Power in an electrical context refers to the rate at which electrical energy is transferred by an electric circuit. One watt is defined as one joule per second and is used to describe the amount of electrical energy consumed or generated in a circuit. In electrical systems, voltage (measured in volts) is the potential difference that pushes electric charges through a circuit, while current (measured in amperes) refers to the flow of electric charges. Resistance (measured in ohms) quantifies how much an object opposes the flow of electric current. While these units are important in understanding electrical systems, they each measure different parameters and do not represent power directly. Watts specifically capture the rate of energy transfer, which is essential in various applications, including calculating the consumption of electrical devices.
