Two batteries of emf \(\varepsilon_1\) and \(\varepsilon_2\) \((​​\varepsilon_2 > \varepsilon_1)\) respectively are connected in parallel as shown in the figure.

          

1. The equivalent emf \(\varepsilon_{eq}\) of the two cells is between \(\varepsilon_1\) and \(\varepsilon_2\) i.e, \(\varepsilon_1<\varepsilon_{e q}<\varepsilon_2\)
2. The equivalent emf \(\varepsilon_{eq}\) is smaller than \(\varepsilon_1\)
3. The \(\varepsilon_{eq}\) is given by \(\varepsilon_{e q}=\varepsilon_1+\varepsilon_2\) always
4. \(\varepsilon_{eq}\) is independent of internal resistances \(r_1\) and \(r_2\)
