The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second.
The rate at which an electrical device converts energy from one form to another is called electrical power. The rate at which electrical energy is changed to another energy form electrical power.
