Homework Statement
Homework Equations
Vc = ( Initial Voltage - Final Voltage ) e(-RC/t) + Final Voltage
3. The Attempt at a Solution
I got the answer through Laplace but am not getting through time domain analysis.
Given q across C is 2.5mC
C = 50micro F
q = CV
So V = 50V
Initial voltage = 50V
Final voltage = 100V since C will be open circuit on steady state.
Req = 10 ohm
Ceq = 50 micro F
RC = .0005
1/RC = 2000
So applying the underlined formula I get Vc = ( 50 - 100) e(-2000t) + 100
Ic = C dV/dt = 50 micro times (-50 * -2000) e(-2000t)
Ic = 5e(-2000t)
Book answer is A.
