WebSimilar to the way that electromotive force (EMF) drives a current of electrical charge in electrical circuits, magnetomotive force(MMF) 'drives' magnetic flux through magnetic circuits. The term 'magnetomotive force', though, is a misnomer since it is not a force nor is anything moving. It is perhaps better to call it simply MMF. WebThe circuit shown in Fig. E25.30 contains two batteries, each with an emf and an internal resistance, and two resistors. Find (c) the potential difference Vac of point a with respect to point c. WebOhm's law says that if you take any material, like let's say, windings of a wire and if we apply a potential difference across the ends of that, so let's say the potential difference across the ends of this wire is V, and because of this, a current starts running over here, let's call that current as I. rubber stamping greeting cards
