The resistance of one turn of a loop of an ac generator is 1Ω. There are 10 turns in the loop's area is 0.16 m2. The loop rotates with a constant frequency of 50 Hz in a uniform magnetic field of 10-T. You task is to
1. Calculate the maximum induced emf.
2. Calculate the maximum induced current when a very small resistance is attached to the output of the generator.
3. Plot the emf waveform showing the time scale and wave variation between the extreme values.
