Question

Given a generator with 566 circular loops of radius 0.11 meters made of 2.1 mm diameter copper wire, with an applied magnetic field of 0.33 T that spins at 847 rev/s.

a) What is the V_rms produced?

b) If the generator supplies an average of 46 MW to a town 37 km away through 2 wires with a linear resistance of 0.28 Ω/km, what is the percentage of power loss in the transmitting wires if the power is not transformed?

c) What would the number of turns ratio be in a transformer if we were to step the voltage to 611 kV? Is this a step-up or step-down transformer?

d) What is the percentage of power loss in the wires if we transform it before transmitting it along the wires?
