Practice Question
Consider two cells of emf \(e_1\) and \(e_2\) with internal resistances \(r_1\) and \(r_2\) , respectively. The two cells are connected in parallel by connecting their positive terminals together and connecting their negative terminals together.

The combination is equivalent to a single cell with emf given by :

Select one correct option:

(\(e_1r_2+e_2r_1\)) / (\(r_1+r_2\)) Correct 💪 In-correct 🧐
(\(e_1r_1+e_2r_2\)) / (\(r_1+r_2\)) Correct 💪 In-correct 🧐
(\(e_1r_2\)) / (\(r_1+r_2\)) Correct 💪 In-correct 🧐
(\(e_2r_1\)) / (\(r_1+r_2\)) Correct 💪 In-correct 🧐
