Question

A cell E 1 of emf 6 V and internal resistance 2 Ω is connected with another cell E 2 of emf 4 V and internal resistance 8 Ω (as shown in the figure). The potential difference across points X and Y is:, 10 . 0 V, 5 . 6 V, 2 . 0 V, 3 . 6 V

I = 6 - 4 10 = 1 5 A V x + 4 + 8 × 1 5 - V y = 0 V x - V y = - 5 . 6 ⇒ V x - V y = 5 . 6 V
