Ground is the common reference point in an electrical circuit (usually defined as 0 V) and the return path for current; choosing the correct ground is important because it establishes a stable voltage reference, ensures safety, minimizes noise and interference, and prevents ground loops or equipment damage. Examples: earth (safety) ground, chassis/frame ground, and signal or power-supply common (circuit) ground.
