What would happen if a current source is in a RC circuit?
I can't find anything on a RC circuit that is not with a voltage source…This is an ideal DC current source with a resistor and a capacitor all in series. What would happen from t = 0 and on?
With a current source, the series resistor is irrelevant. The current will charge up the C at a constant rate, so the voltage on the C will go up in a straight line ramp.
Voltage is basically 1/C times the integral of i. In numbers, V = (1/C)(i*t)

couldn't say it any better. Bill's got it.
I tried to explain another answer a couple days ago…Guess I flubbed it up pretty bad and caught crap from a dude.
Give Bill the 10 points.
