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
When the time t equals the time constant τ, a specific equation shows that the charge on the capacitor is about 63.2% of its maximum value (Q0). In simpler terms, it takes one time constant for the capacitor to reach around two-thirds of its full charge.
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.

The Principle of Parallel Plate Capacitor. We know that we can give a certain amount of charge to a plate.
