The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. Because these capacitors have a DC value, they are actually storing a lot of energy that never gets used.

Explanation of what a transmission line is, and the conditions under which it exists. Uses lumped element model to derive differential equations and manipulates the equations to get telegraph equations. Uses solutions to telegraph equations to get characteristic impedance and propagation constant and looks at matched and unmatched load cases.
