why grounding req low resistance path

grounding

Your Answer

The electric current has tebdency to flow through the low resistance path. As we know ground act as a zero potential. Current has tendency to flow from high potential to low potential. When fault accurs on a particular machine high short circuit current will flow which may damage the machine.. so we need to surpressed that current,for that purpose grounding is done.If grounding resistance is not low then the current will not surpressed..
