Which measurement describes the rate at which electrical energy is consumed or produced?

Power is the rate at which electrical energy is used or created. It tells you how quickly energy is being delivered to a device or generated by a source. In practical terms, power is measured in watts, and in many DC situations it equals voltage times current (P = V × I). This shows why a device with a certain voltage and current is consuming energy at that specific rate. The other terms describe different electrical properties: current is the amount of charge flowing per second, not energy rate; resistance is how much a component resists current, measured in ohms; capacitance is how much charge a capacitor can store per volt, measured in farads.
