Capacitors - Technical MCQs

Q1:

What is the dc charging/discharging time constant for the circuit?

A 294 ps

B 13.5 ms

C 21.25 ms

D 2.16 Gs

ANS:C - 21.25 ms

It asks the charging or discharging time w/c is the same time constant. Not the total charging + discharging time. 8.5K X 2.5 uF = 21.25ms.
