Time Response of Reactive Circuits

Q1:

Referring to Problem 5, how long will it take the capacitor to discharge if the internal resistance of the pulse source is 100 ?

A 300 s

B 600 s

C 900 s

D 1.5 ms

ANS:D - 1.5 ms

Final capacitor voltage=0 volt, after complete discharge.

Vc(t) = Vc(infinity)+(Vc(initial)-Vc(infinity))e^-t/RC---------eq(1)
Vc(t) = 0, Vc(infinity)=0,Vc(initial)=some volts calculated from question no 5, RC=100*1.5*10^-6.
Put all values in eq(1) and then find t.
