Inductors

Q1:

You could decrease the time constant of an RL circuit by

A adding a resistor in parallel with the circuit resistance

B adding an inductor in series with the circuit inductance

C decreasing the amplitude of the input voltage

D exchanging the position of the resistor and inductor in the circuit

ANS:B - adding an inductor in series with the circuit inductance

If you add inductor in series and then you have to go for procedure to find time constant. So in that procedure you have to short voltage source and finally inductor will comes parallel and equivalent inductance will reduce.
