Homework Statement
A voltmeter of resistance 150kilo Ohms is connected across a 50 micro F capacitor. If at time t= 0 the voltmeter reading is 20V. Find
a) charge on capacitor at time t=o
b) voltmeter reading after 10s
c) the time which must elapse after t = o before 95% of the energy stored has been dissipated
Homework Equations
Q=cv
E=1/2 cv^2
The Attempt at a Solution
a) I used Q = cv
b) I used V = (Vo)(e) - (t/RC) formula but not getting the correct answer
c) I tried a bunch of things but didn't even get close to the answer.
So can someone show me how to solve (b) and (c).
Thanks!
