Free QuoteWhat is the capacitance of a grounded capacitor? 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. So it means that the capacitance of a grounded capacitor is Infinite. Why does only one side of a capacitor charge up?

Free QuoteWhen one of the plates of an isolated capacitor is grounded, does the charge become zero on that plate or just the charge on the outer surface become zero? The charge on that plate becomes the same as the charge on Earth.
After making contact, the plate in contact with the Earth then has the same potential as the Earth. But no charges flow because there's not a complete circuit, and because the charges on either plate are attracting each other and holding them to the inside plate surfaces. The capacitor is still a net neutral object (as it the Earth).
When a conductor is grounded, then any excess electrons on it go into the ground. Is this correct? If so, why? Assuming that they do go into the ground, the conductor now has no charge and therefore produces no field. So the integral of -E dr from infinity must be zero. Is this why the potential of a grounded conductor is zero? That is correct.
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.
The conductors may be so charged by connecting them to the two terminals of a battery. Q is called the charge of the capacitor, though this, in fact, is the charge on one of the conductors – the total charge of the capacitor is zero. The electric field in the region between the conductors is proportional to the charge Q.
If the conductor is not in any external electric field, then the excess charge flows to the ground to make the conductor's potential zero, and that is why the integral will be zero, if the potential is set to be zero at infinity. Suppose some positive charge is induced on one side of it, and so there is negative induced charge on the other side.
