WebThe change in electric potential energy of the charge is thus. 18.21 − ΔUE = Wdone by E-field = Fd = qE(xf − xi) or. 18.22 ΔUE = − qE(xf − xi). This equation gives the change in electric potential energy of a charge q when it moves from position xi to position xf in a constant electric field E. WebAnd the formula looks like this. So to find the electrical potential energy between two charges, we take K, the electric constant, multiplied by one of the charges, and then multiplied by the other charge, and then we divide by the distance between those two charges. We'll call that r.
