Top Most 15+ What Is An Emf In Physics

1.Physics - Electromotive Force - University Of Birmingham

Electromotive force (EMF) is equal to the terminal potential difference when no current flows . EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through.
