So for capacitors, if a capacitor is polarized (has a + and - node), then all you need is to make sure that the voltage at the + node is greater than or equal to the voltage at the - node. You do NOT have to connect the - node to ground.
The amount of charge (Q) a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size. A system composed of two identical, parallel conducting plates …
When an ac voltage is applied to a capacitor, it is continually being charged and discharged, and current flows in and out of the capacitor at a regular rate, dependent on the supply frequency. An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so …

When reactive impedance of the capacitor in the circuit is close to the ohm value of the resistor, we do see a 90d voltage phase difference between capacitor sides.

The capacitance of a capacitor is the amount of charge that can be stored per unit voltage. The energy stored in a capacitor is proportional to the capacitance and the voltage. When it comes to electronics, the significant components that serve as the pillars in an electric circuit are resistors, inductors, and capacitors.
Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely. For the capacitor to charge up to the desired voltage, the circuit designer must design the circuit specificially for the capacitor to charge up to that voltage.
To see why it''s said that a capacitor ''resists'', or ''objects to'' changes in voltage at its terminals, it''s useful to compare its behaviour with a resistor (don''t confuse the ''resists'', meaning ''tries to stop'', with anything to do with the component ''resistor''). If you have 10v ...
