Two batteries of emf \epsilon_1 and (\epsilon_2 > \epsilon_1) and internal resistances r_1 and r_2 respectively are connected in parallel as shown in figure.

Correct Answer is : Two equivalent emf εeq of the two cells is between ε1 and ε2 i.e. ε1 < εeq < ε2

Two equivalent emf \epsilon_{\eq} of the two cells is between \epsilon_1 and \epsilon_2 i.e. \epsilon_1

The equivalent emf \epsilon_{\eq} is smaller than \epsilon_1

The \epsilon_{\eq} is given by \epsilon_{\eq} = \epsilon_1+\epsilon_2 always

\epsilon_{\eq} is independent of internal resistances r_1 and r_2
