Does voltage increase or decrease with distance? If you increase the distance between the two plates electric field does not change just because electric field= surface charge density/ epsilon. so E=V/D gives increment in V as D increses so that electric field remain same. The explanation is simple. Therefore increasing the distance increases the voltage. […]
