10 identical cells, each of emf 12V and internal resistance 0.1Î©, are joined in series. Out of these , 3 cells are wrongly connected, i.e., their terminals are connected in reverse of that required for series connection. Let Îµ₀ be the emf of the resulting battery and r₀ be its internal resitance,

3 wrong 6 right
But 3 wrong will nuetrelize 3 rite
Therefore only 3battery will be providing e0
Îµ0 = 36V
The internal resistance will add therefore r₀ = 1Î©
