Two batteries of emf $ \varepsilon_1 $ and $ \varepsilon_2 $ ($ \varepsilon_2 \varepsilon_1 $) and internal resistances $ r_1 $ and $ r_2 $ respectively are connected in parallel as shown

Question

Two batteries of emf $ \varepsilon_1 $ and $ \varepsilon_2 $ ($ \varepsilon_2 > \varepsilon_1 $) and internal resistances $ r_1 $ and $ r_2 $ respectively are connected in parallel as shown in figure.

Accepted Answer

The equivalent emf $ \varepsilon_{eq} $ of the two cells is between $ \varepsilon_1 $ and $ \varepsilon_2 $, i.e., $ \varepsilon_1 < \varepsilon_{eq} < \varepsilon_2 $.

Answer

The equivalent emf $ \varepsilon_{eq} $ is equal to $ \varepsilon_1 $.

Answer

The equivalent emf $ \varepsilon_{eq} $ is equal to $ \varepsilon_2 $.

Answer

The equivalent emf $ \varepsilon_{eq} $ is greater than $ \varepsilon_2 $.
