To calculate the energy stored in a capacitor, we calculate the work done in separating the charges. As we separate more charges, it takes more work to separate even more, due to increased repulsion. Hence, to find the total work done, one needs to integrate.
The ratio of a sinusoidal voltage to a sinusoidal current is called "impedance". This is a generalization of Ohm''s Law for resistors. We derive the impedance of a resistor, inductor, and capacitor.
So, we know that the Inductor Equation is the voltage across an inductor is a factor called L, the inductance, times di, dt. So the voltage is proportional to the slope or the rate of change of current. Let me do a quick review of the two letters that are used as variables for inductors.

How does an RC circuit respond to a voltage step? We solve for the total response as the sum of the forced and natural response. The RC step response is a fundamental behavior of all digital circuits. Written by Willy McAllister.
