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.
If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is equivalent to about 5 time constants or 5T.
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
The supply has negligible internal resistance. The capacitor is initially uncharged. When the switch is moved to position \ (1\), electrons move from the negative terminal of the supply to the lower plate of the capacitor. This movement of charge is opposed by the An electrical component that restricts the flow of electrical charge.
When a charged capacitor is connected to a resistor, the charge flows out of the capacitor and the rate of loss of charge on the capacitor as the charge flows through the resistor is proportional to the voltage, and thus to the total charge present. so that is the initial charge on the capacitor (at time t = 0).
This is because resistance represents an impedement. It slows down and lessens current, so that charging is slower, and, thus, the resultant voltage across the capacitor will be less than with a lesser resistance. Capacitance, C - C is the capacitance of the capacitor in use.

Capacitor Charging Equation
More charged capacitor means more resistance in the circuit, because a fully-charged capacitor acts as an open-circuit. The capacitor is reaching its limit when the time taken is higher than the ten time-constant (5𝜏). From the equation for capacitor charging, the capacitor voltage is 98% of voltage source. This time, the capacitor is said to be fully-charged and t = ∞, i = 0, q = Q = CV ...

6.1.2: Capacitance and Capacitors
The reason is because the internal resistance of a typical digital voltmeter is many orders of magnitude lower than the leakage resistance of the capacitors. As a result, charge will be transferred to the meter, ruining the measurement. It would be akin to trying to measure the voltages across a string of resistors, each in excess of 100 M(Omega), with a meter whose …
