Hence, for any given time, there exist a different value of current and voltage according to the nature of the wave of alternating current. V rms = 0.707 v o and i rms = 0.707 i o in north america, the rms voltage is about 120 volts. An alternating voltage can be generated either by rotating a coil in a uniform magnetic field at a constant speed or by rotating a uniform magnetic field within a stationary coil at a constant speed.
