Nearer to the charge are the equipotential surfaces, thus when the forces increase proportionately the charges come near.
- The relationship between the electric field and potential due to charge is given as E = dV/R.
- Thus if dV is constant and R is inversely proportional to E. Therefore, all equipotential surfaces are closer at a higher value of E.
- For any charge E is higher near load thus equipotential surfaces are closer to the charge. On stepping away from the charge, they start to spread out.
