5.15: Changing the Distance Between the Plates of a Capacitor
If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same?

The current in the discharge process of a capacitor is proportional to the rate of voltage change. Specifically, when a capacitor is discharged, the voltage at both ends is directly related to the rate of change of the current, and the faster the voltage changes, the greater the current. This relationship can be described as follows: i(t)= dq/dt=C dU/dt. Where …

How Capacitors Discharge: Exploring the Process
As water flows out, the water level (voltage) gradually decreases until it reaches zero. To understand the discharging process in capacitors, we need to consider two important factors: the time constant and the discharge curve. Time Constant. The time constant, denoted by the symbol τ (tau), represents how quickly the voltage across the capacitor decreases during the …
Charging and discharging a capacitor. Why current slows down?
Initially the whole of the voltage drop appears across the resistor and none across the capacitor. Charge then flows through the resistor onto the capacitor plates where it accumulates. This increases the PD across the capacitor and at the same time decreases the PD across the resistor. At every instant the sum of these 2 PDs equals the PD ...
