Potential difference VS Electromotive Force - A Level Physics

WebThe meaning of ELECTROMOTIVE FORCE is something that moves or tends to move electricity; especially : the apparent force that drives a current around an electrical circuit and that is equivalent to the potential difference between the terminals of the circuit. WebThe electromotive force, known as emf, is the terminal potential difference of a source when there is no current flow. Internal resistance is the resistance to current flow inside the source itself. But, importantly, how do we calculate these values? Let’s find out. clinic hannover city
