Inductors - Technical MCQs

Q1:

If the switch is moved to position 1 in the given circuit, how long will it take for the current to reach its maximum value?

A 72.5 mu.gifs

B 532 mu.gifs

C 610 mu.gifs

D 833 mu.gifs

ANS:B - 532 mu.gifs

At position 2 inductor is discharging.

Before coming to position 1 inductor is completely discharged.

Its general formula for complete charging of capacitor and inductor 5T.

5*L/R=5*0.1/940=532us.
