In summary, the time constant in parallel plates is the time it takes for the capacitor to reach 63.2% of its fully charged voltage when a constant voltage is applied. It can be calculated by multiplying the capacitance by the resistance in the circuit. It is important to keep the capacitor constant when calculating the time constant in order to accurately compare results. Changing the distance between the parallel plates affects the capacitance and therefore the time constant. However, the time constant cannot be used to determine the size of the capacitor as other factors also play a role.

How can a time constant, in parallel plates, be the original value without changing the capacitor?
