ANSWER:
Problem 46P
Solution 46 P
Step 1 :
Introduction :
In the question, we need to find an expression for the induced emf as a functions of time and plot a graph of current and induced emf as function of time for t=0 to
In the second part we need to find maximum emf , and the current when the induced emf is maximum
In the third part, we need to find the maximum current and induced emf when the current is maximum
