Physics Electromagnetism Electric Potential Energy and Potential

	The Potential of a Charged Conductor:
	The surface of a charged conductor in electrostatic equilibrium is an equipotential surface. Since the electric field is zero inside the conductor, we can conclude from the relationship Er = -dV/dr that the electric potential is constant everywhere inside the conductor and is equal to its value at the surface. The Electrostatic Accelerator: These are the machines which use electric energy to accelerate the charge particles. They can serve as the source of ions. The example of such kind of accelerators isVan de Graf generator . Besides this, there are other accelerators as well: Some of the equipotential lines created due to some point charges are shown below: (i) Cyclotron (ii) Linear Accelerator (iii) Pelletron Accelerator Following is a figure showing a column view of pelletron accelerator.
