Voltage series feedback, also called series–shunt feedback, is a commonly used feedback topology where: Output voltage is sampled (shunt sampling) Feedback is applied in series with the input (series mixing) It is widely used in voltage amplifiers such as op-amp …

The winding factor is an important concept in the analysis and design of an alternator (synchronous generator). It accounts for the effect of distribution of windings and short-pitching (chording) on the generated EMF. Since practical windings are not concentrated in …
