A small resistance allows the capacitor to discharge in a small time since the current is larger. Q factor edit the quality factor or q of a capacitor is the ratio of its reactance to its resistance at a given frequency and is a measure of its efficiency.

In fig 421 when the switch is changed from position a to position b the capacitor voltage tries to charge to the same voltage as the battery voltage but unlike the resistor circuit the capacitor voltage cant immediately change to its maximum value which would be e.

Dc capacitor resistance. Due to the skin effect ac resistance are more in ac circuits than dc supply in dc circuits. The capacitor therefore has a finite parallel resistance and slowly discharges over time time may vary greatly depending on the capacitor material and quality. Likewise when the supply voltage is reduced the charge stored in the capacitor also reduces and the capacitor discharges.
Which one is more ac or dc resistance. Similarly a small capacitance requires less time to discharge since less charge is stored. A small resistance r allows the capacitor to discharge in a small time since the current is larger.
As we know that frequency in dc supply is zero so there is no skin effect a behavior of alternating current to flow through the surface ie. The resistance of a capacitor in a dc circuit is regarded as an open connection infinite resistance while the resistance of an inductor in a dc circuit is regarded as a short connection zero resistance. Capacitive reactance in the rc network tutorial we saw that when a dc voltage is applied to a capacitor the capacitor itself draws a charging current from the supply and charges up to a value equal to the applied voltage.
Similarly a small capacitance requires less time to discharge since less charge is stored. Outer layer of a conductor instead of the core of the wire. In the first time interval after the switch is closed the voltage falls to 0368 of its initial value since.
