Capacitor charging time can be defined as the time taken to charge the capacitor, through the resistor, from an initial charge level of zero voltage to 63.2% of the DC voltage applied or to discharge the capacitor through the same resistor to approximately 36.8% of its final charge voltage. The capacitor charge time formula can be expressed as:
The charge of a capacitor can be changed by connecting it to a DC or AC source. In this article, we will look at the charge time of the capacitor and the voltage across the capacitor during the charging process. The charge time of a capacitor depends on its capacitance and the resistance of the circuit into which it is connected.
This calculator computes for the capacitor charge time and energy, given the supply voltage and the added series resistance. This calculator is designed to compute for the value of the energy stored in a capacitor given its capacitance value and the voltage across it. The time constant can also be computed if a resistance value is given.
Voltage at time ‘t’ while discharging: The time constant, RC, is the time it takes for the voltage across the capacitor to charge or discharge 63.2%, which is equal to e-1. The amount of electric charge that has accumulated on the plates of the capacitor can be calculated if the voltage and capacitance are known.
The discharge of a capacitor is exponential, the rate at which charge decreases is proportional to the amount of charge which is left. Like with radioactive decay and half life, the time constant will be the same for any point on the graph: Each time the charge on the capacitor is reduced by 37%, it takes the same amount of time.
The other factor which affects the rate of charge is the capacitance of the capacitor. 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%).
