Efficiency of an Electric Motor
... The electrical energy in a wire is stored in the electric field between the free electrons in the wire. An electric motor converts this energy to mechanical work, by using it to spin a shaft that can be attached to a large number of mechanical devices (such as the drive axle of a car). The electric ...
