ae / Power in a capacitor: the rate at which energy is being stored in (+) or removed from (-) the electric field. Why is this? It makes sense if you think in terms of energy. A resistor converts electrical energy to heat, …
Experiment #2: Oscillation and Damping LRC Circuit
impedance of the capacitor decreases with frequency, and so does the voltage measured on the capacitor. The RC circuit can therefore be used as a "low pass" filter- where signals with high

The voltage across a capacitor is V C = q/C, and the current through it is i = dq/dt. For an inductor, the voltage is V L = L(di/dt). For a capacitor, then, the voltage is the integral of the current, while for an inductor it is the derivative of the current.
