1) A 240-loop circular armature coil with a diameter of 11.2 cm rotates at 100 rev/s in a uniform magnetic field of strength 0.40 T . What is the rms voltage output of the generator?
2) Suppose 51 kW is to be transmitted over two 0.110 Ωlines
Estimate how much power is saved if the voltage is stepped up from 190 V to 1900 V and then down again, rather than simply transmitting at 190 V . Assume the transformers are each 99% efficient.
