Answer to Question #325527 in Physical Chemistry for Mia

Question

What is meant by EMF of a cell? How is it measured.

Answer 1

Electromotive force (EMF) is equal to the final potential difference when no current flows. EMF and potential difference at terminals (V) are measured in volts, but they are not the same. EMF is the amount of energy (E) that the battery transmits to each pendant charge (Q) passing through it.
