A:
If your answer for L is correct, enter the value 1 below. If it
is not correct, and you have used all allowed submissions, enter -1
below and use L = 15.1 H for the remainder of the
problem.
ENTER 1 IF CORRECT, -1 IF INCORRCT
B:
What is the time constant for this circuit?
𝜏 = s
C:
How long after the switch is closed will the current be 70%
of its final value?
t = s
D:
What is the back emf of the inductor at this time in past
C?
back = V
E:
When t = 2 s after the switch is closed, what is the
stored energy in the inductor?
U = J
