AI Customer ServiceThis charging (storage) and discharging (release) of a capacitors energy is never instant but takes a certain amount of time to occur with the time taken for the capacitor to charge or discharge to within a certain percentage of its maximum supply value being known as its Time Constant ( τ ).
In both charging and discharging processes of a capacitor through a resistance, the current always decreases from its maximum value to zero. What is discharging of a capacitor? The discharging of a capacitor is the process through which stored charge within the capacitor is released.
Charging and Discharging of Capacitor Derivation Charging and discharging of capacitors holds importance because it is the ability to control as well as predict the rate at which a capacitor charges and discharges that makes capacitors useful in electronic timing circuits.
So, the charge on the capacitor will only become zero after an infinite amount of time. The Time Constant is like the timer for a capacitor in a circuit. It's represented by the symbol CR. If CR is much smaller than 1, the capacitor quickly reaches its final charge.
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.
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.
