Are Both Formulas for Work Done in an Electric Field Correct?

[Suyash Singh]

work done in taking positive charge from A to B in electric field E=
potential energy at B - potential energy at A
OR
potential at A-potential at B
Am i correct in both formula?

No, your second formula is incorrect. Since we have to do work on the charge, we have to take difference of final potential to initial potential. Thus, your first formula is correct.

work done in taking positive charge from A to B in electric field E=
potential energy at B - potential energy at A
OR
potential at A-potential at B
Am i correct in both formula?

You are asking of both formulae are right for the same situation? I don't think you can mean that because one must be wrong. Do you need to reword your question? The change in potential is the opposite sign if the journey is in the other direction. (That's sort of obvious really)

thankyou.
