Question

You have a simple electric generator power by turbines in a dam. The generator has 600 loops in its circular coil with radius 0.5 m. The magnetic field used in the generator is 0.70 T.
(a) If the push of the water rotates the coil loop at a rate of 1 rotation per minute, what is the peak voltage output of the generator?

(b) If you want to use this generator at the rotation rate found in the previous part to generate enough electromotive force to match the 120-V RMS power that we use in our houses, how many loops would you need in the coil?

Answer 1

The above question is solved using the concept of induced emf in the generator.
