Published by Henry, theengineeringknowledge.com, May 20, 2020 The basic difference between grounding and earthing is that in grounding the conductor through which the current is flowing is connected with the ground while in earthing the conductor through which the current is not flowing is attached with the ground. In this post, we will have aContinue reading “Difference Between Grounding and Earthing”
