) The equipotential lines are the dotted lines in the diagram below. The circles represent sets of points that are equidistant from point P and only serve to give you a sense of scale. The circle on which Point A is located represents a distance of 1 cm from point P. -40V -30V -20V -10V -40V -30V -20V - 10V .
