The alexkor zero back emf
Webv. t. e. In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, [1] [2] denoted or ) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf [3] by converting other forms of energy into electrical energy. [3]
