Power is a way to describe how quickly energy is transferred from one store to another or one object to another. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. For a given amount of electric current, which resistor will dissipate the greatest amount of power: Answer with unit of measure: Which heater has the highest power rating?
