Which term describes the rate at which electrical energy is used?

In physics and electricity, power is defined precisely as the rate at which energy is consumed, generated, or transferred. In an electrical circuit, it is measured in watts, where one watt equals one joule of energy used per second. While voltage (electromotive force), current (flow of electrons), and resistance (opposition to flow) are key properties of a circuit, they do not measure the rate of energy usage. Power is the mathematical product of voltage and current (P = V x I). When you look at a light bulb rated for 60 watts, you are seeing its power rating, which is the exact rate at which it transforms electrical energy into light and heat.
