Electric potential is the work which you need to do to bring a positive point charge to a distance, r, from the charge making the field. The potential at infinity is zero. The potential is largest right next to the charge. Calculating the potential ...
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. ...
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. Assume that a +ve charge is located at a point then it will...
