ε=20V I S i Ry=150 Ω www R=50 Ω ic |C=1uF
see the image:
The question asks for the currents of i1 and ic at time = 0; Then it asks the currents for i1 and ic at infinite time.
In the first case, where time is 0, ic = 0.4 A and i1 = 0, because, according to the answer, all the current passes trough the capacitor, as it is short circuited, and not the resister.
At the second case, where time = inf, ic = 0, because there is no more current passing through it, and i1 = 0.1A.
THE QUESTION IS:
Why there is no charge passing through i1 at t = 0, and why there is no charge passing through ic at time t = infinite?
As long as I know, when the capacitor is fully charged it does not allow charge to pass trough it, but in some places I find that it allows all the current to flow trough it. Please clarify and let it clear, you may use a real life example to make it simpler.
