Problem 86

The voltage across an inductor reaches its maximum value 25 ms before the current supplied by the generator reaches its maximum value. What is the lowest possible frequency at which the generator operates?

Step-by-Step Solution:
Step 1 of 3

Chapter 23: Magnetic Flux and Faraday’s Law of Induction Flux=BAcos (thet)  o Unit is Weber (Wb) o B is magnetic field o A is area  Magnetic flux if used in the calculation of the induced emf  Faraday’s Law: an emf is induced only when the magnetic flux though a loop changes with time Change∈ flux o Change∈time ) emf =−N ¿  Lenz’s law: an induced current always flows in the direction that opposes the change that caused it.  Electric field caused by the motion of a rod: o E=Bv  When a switch is added to a circuit and when the switch is closed, the current starts to increase immediately. As time goes on, the current increases more slowly and the potential difference across the inductor decrea
