WebTwo cells each having an emf of 1.5v and an internal resistance of 2 ohms are connected in parallel. Find the current in each case when the cells are connected to a 1 ohm’s resister Expert's answer Here Two cells connected in parallel and then 1\varOmega 1Ω connected in series is analysed completely. WebIn reality, when we measure we measure 0.8 A. Hence the resistance is: R = V I = 10 Ω. So the internal resistance of the battery in this case is: R i n t e r n a l = R t o t a l – R e x t e r n a l. Substiuting the values in the above equation, we get: R i n t e r n a l = 10 Ω – 8 Ω = 2 Ω. WebFour cells, each of e.m.f. 1.5 V and internal resistance 2.0 ohms are connected in parallel.
