Which Equation Is Used To Calculate The Electric Potential In An Electric Field From A Point Charge? V = Kq Over D Squared V = Kq Over D V =Delta U Over Q V = Delta U Over E. In this case, the electric field is not uniform, so your first equation δv = ed is not correct. The formula for calculating the electric potential (v) at a point due to a point charge (q) is given by:

In this case, the electric field is not uniform, so your first equation δv = ed is not correct. The formula for calculating the electric potential (v) at a point due to a point charge (q) is given by: @$$\begin {align*}v = \frac {kq} {r}\end {align*}@$$ where:
