Q. No.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 \(r_2\) |
