11. DISCHARGING A CAPACITOR At first, it is easy to remove charge in the capacitor. Coulombic repulsion from charge already on the plates creates a force that pushes some of the charge out of the capacitor once the force (voltage) that placed the charge in the capacitor is removed (or decreased). As more charge is removed from the plates of the …

Since charge builds up on a capacitor rather than flowing through it, charge can build up until the point that the potential difference ΔV=Q / C balances out the external voltage (electromotive force of the source) pushing charge onto the capacitor. The discharge of a capacitor in a RC circuit is the inverse process of capacitor charging ...
Capacitor Discharge Equations. This exponential decay means that no matter how much charge is initially on the plates, the amount of time it takes for that charge to halve is the same; The exponential decay of current on a discharging capacitor is defined by the equation: Where: I = current (A); I 0 = initial current before discharge (A); e = the exponential function
We can plot an exponential graph of charging and discharging a capacitor, as shown before. However, by manipulating the equation for discharging, we can produce a straight line graph: Take logs of both sides: This is in the form …

At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero; As a capacitor discharges, the current, p.d. and charge all decrease exponentially. This means the rate at which the current, p.d. or charge decreases is proportional to the amount of current, p.d or charge it has left
The capacitor discharge continues until the capacitor voltage drops to zero or is equal to the applied voltage. Applying the Charge In the figure below, the capacitor is neutral with no charge because it has not been connected to any source of applied voltage and there is no electrostatic field in the dielectric.
