However, electromotive force itself is not a physical force, and ISO/IEC standards have deprecated the term in favor of source voltage or source tension instead (denoted U s {\displaystyle U_{s}} ). An electronic–hydraulic analogy may view emf as the mechanical work done to water by a...
electromotive force Physics a. a source of energy that can cause a current to flow in an electrical circuit or device b. the rate at which energy is drawn from this source when unit current flows through the circuit or device, measured in volts. Collins Discovery Encyclopedia, 1st edition...

A general concept of the electromotive force for arbitrary processes may be defined, but the generalization is not unique. Here we define the electromotive force as the work done to a positive unit charge when the charge moves along the trajectory instantly. This definition is valid for induced ...
