The rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge.
A capacitor has an infinite resistance (well, unless the voltage gets so high it breaks down). The simplest capacitor is made from two parallel plates with nothing but space in between - as you can guess from its electronic symbol. In a DC circuit, a capacitor acts as an open circuit and does not permit current to pass.
An ideal capacitor in series with resistance is called Equivalent series resistance of the capacitor. The equivalent series resistance or ESR in a capacitor is the internal resistance that appears in series with the capacitance of the device. Let's see the below symbols, which are representing ESR of the capacitor.
Real capacitor has both series and parallel resistance. Fortunately, these stray resistances are usually of modest impact (low series resistance and high parallel resistance), much less significant than the stray resistances present in an average inductor.
A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%). The two factors which affect the rate at which charge flows are resistance and capacitance.
In a DC circuit, a capacitor acts as an open circuit and does not permit current to pass. In an AC circuit a capacitor has an effect because it acts as a current reservoir while the current is changing. This can have the effect of smoothing the current spikes so it performs a damping effect.
