Capacitor Discharging
The transient behavior of a circuit with a battery, a resistor and a capacitor is governed by Ohm''s law, the voltage law and the definition of capacitance. Development of the capacitor charging relationship requires calculus methods and involves a differential equation.

What happens to electricity when it goes into the ground?
The Earth itself is the other plate, and atmospheric electricity can charge that capacitor to dangerous voltages. The purpose of a ground wire on each pole is to discharge that capacitor. Learn more about what capacitors are and how they work, and you will have a better understanding of why the power grid is grounded. $endgroup$

electric circuits
Suppose an inductor is connected to a source and then the source is disconnected. The inductor will have energy stored in the form of magnetic field. But there is no way/path to discharge this energy? …
Does Voltage Change Across a Capacitor?
Capacitors store electrical energy in the form of an electric field between their plates, and they store charge, not voltage or current. When a voltage is applied across a capacitor, it stores charge, which leads to an increase in voltage across the capacitor until it reaches the same voltage as the applied source.
Where does charge from a capacitor go when is discharged?
If you connect a capacitor to a resistor, the charges rush together through the circuit to neutralize each other, and their energy is dissipated as heat through the resistor. The charges end up wherever they normally do in a piece of metal.
Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
Where Does Charge Go When A Capacitor Is Discharged?
Advertisement If a capacitor is discharging, current exits the more positive terminal rather than entering. That''s really all there is to it. When current enters the more positive terminal, power is delivered to the capacitor and, thus, the stored energy increases. How does a capacitor charge and discharge itself? DischargingRead More →
