Ground loop

  "id": "MLC-T-IND-002665",
  "term": "Ground loop",
  "field": "Industrial and trades",
  "definition": "An unwanted current flowing through a conductor connecting two points that are nominally at ground potential but have different actual potentials. This difference creates a voltage, causing current to flow and often resulting in hum or noise in audio and video systems. Proper grounding techniques, such as star grounding, can mitigate this issue.",
