Homework Statement
I know the definition of electric potential is the work done to bring a test charge from infinity to a particular point.
But I read about some question asking the electric potential of a charged conductor,
I wonder what that means, whether it is the potential of the surface of the conductor or otherwise.
Also, I don't understand the concept of bringing a earthed object close to a charged conductor will
decrease the magnitude of potential of that charged object.
eg. my notes mention the induced charge inside the eathed object contrubutes a positive potential
to make the potential of the negative charged conductor LESS negative. Itsn't an earthed object
have zero potential? So how can it contrubute any potential.
