Hello, I am having problems in determining the capacitor current. I am asked to find the equation for v(t). intial conditions are i(0)=40A and v(0)= 40V. L is 12.5mH, R=0.1 ohm , C =0.2F the thing is I cant figure out the relation for Ic. i got v(t)= A1e^-10t+A2e^-40t for second equation i have to derivate and use the relation for ic in terms of ir and i as per the diagram. i sued ic=-ir-i but thats not right because my answer is wrong. please guide me. thanks.
