Electric Power and Energy

Electric power is the rate at which electrical energy is transferred or used in a circuit, typically measured in watts (W). It describes how quickly energy is consumed by devices, like light bulbs or motors. Energy, on the other hand, is the total amount of work that can be done by electric power over time, measured in watt-hours (Wh) or kilowatt-hours (kWh). In electrodynamics, power and energy are fundamental concepts that describe how electric fields and currents interact, enabling everything from household appliances to complex technologies. Understanding these concepts helps in managing energy efficiency and consumption.
