Here we`ll find the initial value of capacitor voltage - Rose
... Its current is the time rate of change of its voltage * its capacitance. Rewrite the equation to solve for what we want. This equation is true at t=0, so replace t with 0 in these cases. If we can find ic(0), we’ll know dvc(0) / dt. ic(0) needs to be defined according to passive sign convention. Not ...
