A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding -type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots). [1] : 112 They are needed to allow appliances with 3-wire power cords to plug into legacy ungrounded (two slot) receptacles found in older ...
Ground and neutral. A shorting bar connecting ground and neutral in Swiss industrial building (outlined in red). A hunk of copper is visible that is designed to be easily connected or disconnected from its place between two screws, rated for 600 A (as stamped on it). We also see the thick wires in standard colors (two yellow/green ground and ...
Phone connector (audio) Phone plug mated in a phone socket. The plug's grooved tip is held firmly by the socket's spring tip contact. When not mated, this spring instead connects to the flat switch contact for detecting a plug. A phone connector is a family of cylindrically -shaped electrical connectors primarily for analog audio signals.

Ground loop (electricity) In an electrical system, a ground loop or earth loop occurs when two points of a circuit are intended to have the same ground reference potential but instead have a different potential between them. [1] This is typically caused when enough current is flowing in the connection between the two ground points to produce a ...
The two-rays ground-reflection model is a multipath radio propagation model which predicts the path losses between a transmitting antenna and a receiving antenna when they are in line of sight (LOS). Generally, the two antenna each have different height. The received signal having two components, the LOS component and the reflection component ...
Ground lift. In sound recording and reproduction, ground lift or earth lift is a technique used to reduce or eliminate ground -related noise arising from ground loops in audio cables. It may also increase or decrease noise from other sources. [1] Activating the ground lift on a particular piece of equipment opens the connection between the ...
In electronics and radio communication, a counterpoise is a network of suspended horizontal wires or cables (or a metal screen), used as a substitute for an earth ( ground) connection in a radio antenna system. It is used with radio transmitters or receivers when a normal earth ground cannot be used because of high soil resistance [1] or when ...
