Electric potential is the work done to move a positive test charge from infinity to a given point within the field.
The electric potential at a particular point in space is the work done in moving a positive charge from infinity to that point. The electric potential at infinity is defined as zero. Electric potential is related to the electric potential energy in that electric potential is the electric pote...
We have derived the potential for a line of charge of length 2a inElectric Potential Of A Line Of Charge. lnV=λ4πϵ0ln(a2+r2+aa2+r2–a) We shall use the expression above and observe what happens as a goes to infinity. But first, we have to rearrange the equation. ...

摘要: From the expression of charge distribution on a charged elliptical rign conductor in Ref.[1],the electric potential and the electric field strength of arbitrary point on the z axis can be obtained.关键词: elliptical ring electric potential electric field strength ...
If the potential at infinity is fraction{-GM}{r}. Then what is the potential at the surface of the earth? Please explain the approach. Why is the potential energy of a spherical conductor U = (1/2)VQ and why not U = VQ?
更新1: I haven't learnt calculus... (this is DSE syllabus) My textbook just mentions 'Consider a positive point charge Q. When infinity is taken as zero potential the electric potential at a position r away from Q is given by ...(the one I stated)更新2: Did you ...
Electrical Potential Due to a Point Charge In an electric field, the electric potential at a specific point can be defined as the amount of work completed to move a positive unit charge from infinity to that point through any path once the electrostatic force is applied. ...
