EMF – V1 – V2 – V3 – V4 = Zero. Thus, the voltages V1 thru V4 arise as a consequence of the EMF and their sum numerically equals the EMF, but since those V1 thru V4 arise as the result of electrical ...

EMF (electromotive force) and potential difference, also known as voltage, are both important concepts in electrical circuits, but they refer to different things. EMF is a measure of the energy per ...
