A simple generator has a coil with area A=0.02m2, which is rotated at frequency f=60Hz (remember that angular frequency is 2*pi*f) in a B=0.5T magnetic field. How many windings (number of turns N) are needed if the generator is to develop an average power of P=0.05kW if the total resistance in the circuit is R=0.14kiloOhms?
N = turns
