Capacitors - Technical MCQs

Q1:

How long would it take the capacitor in the given circuit to completely discharge if the switch was in position 2?

A 22 ms

B 69 ms

C 345 ms

D 420 ms

ANS:D - 420 ms

You guys substituted C = 1x10^-6 F, instead 10x10^-6 F(As given in the question).

So your answer is 42 ms (wrong), instead 420 ms (Correct).
