Capacitor & AC: Questions Answered

[ragavcit]

HI,
How come an AC flows through a capacitor when there is no continuity inbetween its plates??how come the resistance offered by a capacitor changes with frequency??

In 2 words: "displacement current". That should get you started.

This should help as an introduction: http://en.wikipedia.org/wiki/Capacitor

And as I mentioned in your nearby Inductor thread, it's the "impedance" that changes with frequency, not its "resistance".
