What is the unit of measurement for electrical power?

The unit of measurement for electrical power is Watts. This unit quantifies the rate at which electrical energy is converted into another form of energy, such as heat, light, or mechanical energy, within an electrical circuit. Power in an electrical context can be calculated using the formula: Power (P) = Voltage (V) × Current (I), where Voltage is measured in Volts and Current in Amperes. This relationship shows that Watts are derived from the interaction of volts and amperes, making it a key metric for understanding how much energy is being used or produced in an electrical system. Watts are fundamental in various applications, helping to determine the energy consumption of electrical devices and to ensure that electrical systems are appropriately designed for safety and efficiency.
