A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as different colored ...

An Ayrton–Perry winding (named for William Edward Ayrton and John Perry) is a type of bifilar winding pattern used in winding wire on forms to make RF resistors. Its advantage is that the resulting coil of wire has low values of parasitic inductance and parasitic capacitance. [1] Ayrton–Perry windings of resistance wire are used to make ...
Electromagnetic coil. The magnetic field lines (green) of a current-carrying loop of wire pass through the center of the loop, concentrating the field there. An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix). [1][2] Electromagnetic coils are used in electrical engineering, in applications ...
Coil winding technology. In electrical engineering, coil winding is the manufacture of electromagnetic coils. Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill ...
Common-mode rejection ratio. In electronics, the common mode rejection ratio (CMRR) of a differential amplifier (or other device) is a metric used to quantify the ability of the device to reject common-mode signals, i.e. those that appear simultaneously and in-phase on both inputs. An ideal differential amplifier would have infinite CMRR ...
The current I in each winding is related to the applied voltage V by the winding inductance L and the winding resistance R. The resistance R determines the maximum current according to Ohm's law I=V/R. The inductance L determines the maximum rate of change of the current in the winding according to the formula for an inductor dI/dt = V/L. The ...
Transformer types. Transformer with two windings and iron core. Transformer with three windings. The dots show the relative configuration of the windings. Transformer with electrostatic screen preventing capacitive coupling between the windings. In an electric arc furnace, the transformer has a heavy copper bus for the low voltage winding ...
