voltage
As far as I understand, in an AC circuit, a capacitor is supposed to charge as the voltage is increasing, and as soon as the voltage starts decreasing, the capacitor starts to discharge (Since it will be the higher voltage source out of all in the circuit by then).

This gives us the impression, a capacitor might resist a voltage change, but it is basically the speed of voltage change which is defined by the capacitor and its surrounding circuitry. In your example (given all elements are ideal ones) the voltage change will take an infinitesimal time when the switch is put into position 1.

Why do the polarities of the capacitor change while discharging?
The inductor-current cannot change rapidly, and this causes the voltage across the capacitor to, rather than just exponentially settling to zero, instead the ... by generating a voltage that matches the capacitor voltage, so current ramps up from zero (at rate dI/dt = V/L). As the capacitor discharges the voltage drops so the current …
DC Lab
This circuit project will demonstrate to you how the voltage changes exponentially across capacitors in series and parallel RC (resistor-capacitor) networks. You will also examine how you can increase or …
Derivation for voltage across a charging and discharging capacitor
Capacitor Discharge Equation Derivation. For a discharging capacitor, the voltage across the capacitor v discharges towards 0. Applying Kirchhoff''s voltage law, v is equal to the voltage drop across the resistor R. The current i through the resistor is rewritten as above and substituted in equation 1.
