Please log in for more thread options sir, I have a dout about capacitor discharge.Can a charged capacitor discharge by connecting its one terminal and ground without using its other terminal. | ||||

Please log in for more thread options The only way to reduce the voltage of a so-called charged capacitor is by providing a conductive path between the two terminals of that capacitor. Earth, or ground is only conductive to other parts of the earth (and rather poorly). People sometimes refer to a common point in a circuit as "ground". A circuit's "common" only has a conductive path to real ground (earth) if it's connected to ground (earth). Bob | ||||

Sir, If we touch one terminal of the charged capacitor , is current flow through our body to the ground without any contact with other terminal. | ||||

No you *have* to use the other hand to hold the bottle. Likewise the capacitor can only push as much current out of one terminal as it pulls into the other. | ||||

In electrostatics, you can discharge a body by providing a conductive path to earth (or anywhere else); but a capacitor is two charged bodies (plates), holding equal and opposite charges, with an electric field between them. If you connect a conductive path to one plate, only a very small percentage of the stored charge will re-distribute itself. | ||||
