"WebFlowing of electric current through the undesirable paths in an electrical circuit creates ground loops. This phenomenon happens when the electrical piece of equipment has a connection at multiple points on the ground plane. The ground loops induce noise in instrument signal cables. Also, it can overheat the cables & thus it begets a fire hazard. " - Ground loop impedance
