A cell of emf ‘’ and internal resistance ‘r’ sends current 1.0A when it is connected to an
external resistance 1.9Ω. But it sends 0.5A when it is connected to an external resistance of
3.9Ω. Calculate the values of and r.

Answer:
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.
