Suppose one plate of the capacitor is grounded which means there is charge present at only one plate. We know that the potential across the capacitor will be 0, i.e., V=0. And capacitance of the Capacitor will be C=Q/V C=Q/0 implying C=∞ So it means that the capacitance of a grounded capacitor is Infinite.
An equal and opposite amount of charge will accumulate on the grounded one.Case2. Both the plates are initially charged and then one is earthed.Effective intensity outside the capacitor system is zero.There will be no effect on some uncharged body external to the system.
Grounding either pin of a capacitor to frame ground does not necessarily cause a discharge. In fact, it may apply power to some circuit that does not expect it, potentially damaging it.
When a capacitor is being charged, negative charge is removed from one side of the capacitor and placed onto the other, leaving one side with a negative charge (-q) and the other side with a positive charge (+q). The net charge of the capacitor as a whole remains equal to zero.
You are essentially correct. The “floating” wire you have drawn will act as a stray capacitance to ground. Because the shape is a poor shape for a capacitor the capacitance will be very small. So the circuit will look like two capacitors in series, connected to ground, one capacitor being much larger than the other.
In case 2, you still connect one plate to +5V, but leave the other plate floating and neutral. According to my understanding, charge should still build up on the positive side of the capacitor because it's at the same potential relative to the other plate as case 1, and it has the same geometry.
Intuitive approach: if the distance wouldn''t be a factor then you would be able to place the plates at an infinite distance apart and still have the same capacitance. That doesn''t …
