    Graduate How can a grounded conductor have induced charge?

    Thanks willem2 for answering my question. I apologize for creating the confusion by referring to induced charge. I'll try to break the issue into readable points. 1- The author defines capacitance as the proportionality constant relating the potential at surface of the conductor relative to...

    Graduate How can a grounded conductor have induced charge?

    Thanks for your reply and patience. I understand what Gauss's law is, my question is when there is charge on a grounded conductor, the charge will emanate electric field which will give a rise to a non zero potential when a line integral is taken from infinity to the surface of that charge...

    Graduate How can a grounded conductor have induced charge?

    Hello, I came across this topic while reading Principles of Electrodynamics which can be read from this link starting at page 54. Looking at page 56, my question is how could there be induced charge on a grounded conductor ? what happens then to the equation Q = C * V, where Q is charge...
