Inductors

Q1:

What is the approximate time for a complete decay of 400 mA of inductor current, when R = 10 ohms and L = 20 H?

A 10 seconds

B 8 seconds

C 4 seconds

D 2 seconds

ANS:A - 10 seconds

As we Know that
Time Constant for Inductor is
Time Constant=L/R
So Time Constant=20/10=2s
For Complete Decay 5*2s=10s
where 5 is a factor of time constant for complete decay
