the question is to find I(0)- and I(0)+
the I is at the
what I have attempted
finding Req on the right side
I eliminate the capacitor and Req = 12*6/(12+6) = 4
so Vc (0)- = Req/(Req+12) *18 = 9/2
T = Req*c= 4*1/12 = 1/3
so V(t) = 18/4 e^(-3T)
so I (0)- = V(t)/12 = 3/8 e^(-3t)
but I don't know how to find the I(0)+
sorry for bad English and bad picture
thx for replying in advance
