Consider the special situation of a positive level demand q on the origin. To estimate the opportunity attributable to q at a length r in the origin relative into a reference of 0 at infinity (remember that we did the same for potential Power), Enable (P = r) and (R = infty), with (dvec l = dvec r = hat r dr) and use (vec E = frac kq r^2 hat r ). When we Assess the integral
Much more basically, The purpose you end up picking for being zero volts is arbitrary.
