"Hello Forum,\nIn DC circuits, I understand that a ground is a point or an entire conductor where the electric potential is set to be V=0 and the potential V at any other point in the circuit is referenced to that.\n\nHow does the the concept of ground loops work? Why are they not desirable?\n\nWhat about a floating ground? What is floating about it?\n\nThanks,\nFog37"
