What happens when a capacitor is discharged?
Discharging a Capacitor A circuit with a charged capacitor has an electric fringe field inside the wire. This field creates an electron current. The electron current will move opposite the direction of the electric field. However, so long as the electron current is running, the capacitor is being discharged.
How is energy dissipated in charging a capacitor?
energy dissipated in charging a capacitorSome energy is s ent by the source in charging a capacitor. A part of it is dissipated in the circuit and the rema ning energy is stored up in the capacitor. In this experim nt we shall try to measure these energies. With fixed values of C and R m asure the current I as a function of time. The ener
What happens if a capacitor is charged out?
Once the charges even out or are neutralized the electric field will cease to exist. Therefore the current stops running. In the example where the charged capacitor is connected to a light bulb you can see the electric field is large in the beginning but decreases over time.
How to determine leakage resistance of a capacitor while charging/discharging?

Why does a capacitor lose voltage when it starts discharging?
It is important to note that from the instant the capacitor starts discharging, it is losing charge and therefore losing voltage since the potential across the capacitor is proportional to the charge stored in it.
