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.
This way you can evaluate feasibility. Use a bleeding resistor to discharge the cap. It says the Bleed resistor is used for 'safety purposes' where we need to safely discharge the capacitor.. But In my case, it is not the case... I want to automatically discharge the capacitor ONLY when it maximum voltage (2V in this case) is reached..
So long as the battery is connected, the capacitor will just remain charged. Once the battery is removed, if there's some closed loop path between the plates of the capacitor, then the excess charge on one side of the capacitor will use the closed loop to balance out the charge.
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.
Accidentally or carelessly touching the leads of the capacitor after disconnecting the power supply, on the misconception that the absence of a power supply makes it harmless, can bear consequences ranging from mild tingling or burn to fatal electrocution and fire, depending on the amount of charge present in the capacitor.
Manual discharge of capacitors is a critical skill for electronics professionals. The following step-by-step procedure outlines a safe manual discharge method: Verify power is disconnected and capacitor is isolated from the circuit. Select an appropriate discharge resistor based on capacitor voltage and capacitance.
