Charge flow from one capacitor to another

Why and how does charge flow from one capacitor to another capacitor when the two are connected to each other by a conducting wire? I am not able to understand that; why and how does negative charge flow from a capacitor having lower potential difference between its plates to a capacitor having higher potential difference betwe

Undistorted Sinusoidal Signals in a Diode Circuit

In the diode shown, the diodes are ideal except that each is modeled by a voltage source of 0.5V in series with a (diode) resistance of rd = 20, when forward biased. A sinusoidal signal Vs with input impedance Rs=100 is connected to the diode circuit. Determine the maximum value of Vs such that Vo remains sinusoidal, with no dis
