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. If we supply more charge, the potential increases and it could lead to a leakage in the charge. If we get another plate and place it next to this positively charged plate, then negative charge flows towards the side of this plate which is closer to the positively charged plate. As …
9. CHARGING A CAPACITOR At first, it is easy to store charge in the capacitor. As more charge is stored on the plates of the capacitor, it becomes increasingly difficult to place additional charge on the plates. Coulombic repulsion from the charge already on the plates creates an opposing force to limit the addition of more charge on the plates. Voltage across a …

The time constant of a CR circuit is thus also the time during which the charge on the capacitor falls from its maximum value to 0.368 (approx… 1/3) of its maximum value.

It is possible in principle if the inductance (see Chapter 12) of the circuit is zero. But the inductance of any closed circuit cannot be exactly zero, and the circuit, as drawn without any inductance whatever, is not achievable in any real circuit, and so, in a real circuit, there will not be an instantaneous change of current. Section 10.15 will deal with the growth of current in a …
