I know that in electronics, a shunt capacitor decouples the AC signal by effectively shorting it to ground, but in a power system, when a shunt capacitor is used for power factor correction, this doesn't occur. I know that if you calculate the current as if the capacitor were ideal, you only get reactive current at a negative angle, and it would make sense for no real current to be shorted to ground. But the capacitor isn't ideal, there is resistance in the copper wires going to the capacitor.
Why does a shunt capacitor in a power delivery system behave differently than a decoupling capacitor (such as in a 4R biasing circuit)?
