When 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.
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.
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.
No, the fact that one plate is grounded does not mean that there is no charge on that plate. Look up "charging by induction" which leaves a charge on a conductor even though it is grounded. What is your definition of capacitance if the two plates do not carry same amount of opposite charges?
A conductor has the same potential at every point once the charges come to an equilibrium. So, a grounded conductor has potential zero throughout (provided we have chosen the potential thus). This is why we can use the phrase potential of a conductor. That is the difference between talking of the potential of a charge and potential of a conductor.
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.

Live ChatI am working on a textbook problem of a grounded conductor inside a uniform electric field. The textbook states that "grounded" means potential = 0. In my opinion, "grounded" should mean "same potential as infinity". But in this case we can''t set potential at infinity equal zero. So my question is, what is actually the meaning of "grounded".
