 Related Questions Earth has the constant potential so we take it as reference.but in steo & touch voltage we use to calculate voltage of ground in 30 inch. How it is possible if no current can flow through ground? Read Answers (2) | Asked by : shital tikare Latest Answer : Because, the load's are in parallel, if you switch on load due to parallel, total effective resistance decreses. Thus I=(V/R) according to OHM's law relationship the current drawn from the source increases. ... Read Answers (5) | Asked by : Rakesh Sable T.I.T.
