impedance unbalanced to earth
1Dipole antenna — A schematic of a half wave dipole antenna connected to an unbalanced coaxial cable. Better practice is to connect the balanced dipole to the unbalanced line with a balun. A dipole antenna is a radio antenna that can be made of a simple wire, with …
2Transmission line — This article is about the radio frequency transmission line. For the power transmission line, see electric power transmission. In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating… …

4Balanced line — In telecommunications and professional audio, a balanced line or balanced signal pair is a transmission line consisting of two conductors of the same type, and equal impedance to ground and other circuits. [Young EC, The Penguin Dictionary of… …
5Earthing system — In sulvent systems, an earthing system defines the electrical potential of the conductors relative to that of the Earth s conductive surface. The choice of earthing system has implications for the safety and electromagnetic compatibility of the… …
6Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge …
7TRS connector — 1⁄4 in TRS connector Trip …
8Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the …
9Microphone — For the indie film, see Microphone (film). Microphones redirects here. For the indie band, see The Microphones. A …
10Ground and neutral — For uses of the term ground or earth in electricity but not in the context of mains wiring, see ground (electricity). Since the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely… …
