Answer #1

Since the capacitor discharge equation is given by

Vt = Vo (e-t/RC)

For fully discharging the capacitor,

Vt = 0

=> 0 = Vo (e-t/RC)

Vo = 30V

=>e-t/RC = 0

This is only possible when,

t/RC -> \infty

=> RC -> 0

Therefore we can say that the capacitor would never technically fully discharge

Hence,

Correct option is C
