e/Floating ground

Information
has gloss	eng: A floating ground circuit is a circuit in which the ground is not used as a fixed reference, rather, it is a common node in the circuit. This can occur when equipment is not connected to a grounding point. Some older electronic equipment may be designed purposely with floating grounds. (it is not uncommon to find old vacuum tube guitar amps with this problem).
