[Answer] theoretically when a capacitor is charged it will hold its charge indefinitely. Actually it will lose its charge why?

Answer: no such thing as a perfect dielectric. the electrons eventually move from the negative plate to the positive side or leak through causing the capacitor to discharge

theoretically when a capacitor is charged it will hold its charge indefinitely. Actually it will lose its charge why? theoretically when a capacitor is charged it will hold its charge indefinitely. Actually it will lose its charge why? no such thing as a perfect dielectric . the electrons eventually move from the negative plate to the positive side or leak through causing the capacitor to discharge Once the capacitor is “fully- charged ” the capacitor blocks the flow of any more electrons onto its plates as they have become saturated. However if we apply an alternating current or AC supply the capacitor will alternately charge and discharge at a … Once the capacitor is “fully-charged” in theory it will maintain its state of voltage charge even when the supply voltage has been disconnected as they act as a sort of temporary storage device . However while this may be true of an “ideal” capacitor a real capacitor will slowly discharge itself over a long period of time due to the internal leakage currents flowing through the dielectric . A capacitor can keep its charge indefinitely (in theory). That's why with large capacitors it is dangerous to open high voltage equipment even years after they have been disconnected . What you are probably asking is the time the capacitor needs to discharge. It will discarge according to an exponential law. In the case you described (a capacitor feeding a bulb) you … Sun Nov 27 2016 · An ideal capacitor would never lose any charge. Capacitors are made of less than ideal materials and will over time lose some of their charge. Assuming they are not connected to anything else –...
