In moving from A to B along an electric field line, the electric field does 6.4 x 10^-19 j of work on an electron . If phi1 and phi2 are equipotential surfaces, then the potential difference (Vc – Va ) is In moving from A to B along an electric field line the electric field does 6.4 x 10^-19 j of work on an electron .
