Assignment:
Question 1. When its coil rotates at a frequency of 280hz, a certain generator has a peak emf of 75 V.
a) What is the peak emf of the generator when its coil rotates at a frequency of 45 hz?
b) Determine the frequency of the coils's rotation when the peak emf of the generator is 180V.
Question 2. A series RCL circuit is a resonance and contains a varible resistor that is set to 175 ohms. The power delivered to the circuit is 2.6 W. Assuming that the voltage remains constant, how much power is delivered when the varible resistor is set to 562 ohms?
