1 AI A H T B x FIGURE 3 20 Two cells of emf s and in the series 7 7 are their ternal resistances For connections across A and C the combinatio can be considered as one cell of emf and an internal resistance r eq 1 E2 H T E eq E 12 and r F 1 12 eq C VACE IT eq Ir G2 12 Comparing the last two equations we get heline DUAL CAMERA Consider first two cells in series Fig 3 20 where one terminal of by Sourcadeo is joined together leaving the other terminal in either cell Physics Eeq A I If we wish to replace the combination by a single cell between A and C of emf and internal resistance r we would have eq eq Teq 3 63 3 64 3 65 In Fig 3 20 we had connected the negative electrode of the first to the positive electrode of the second If instead we connect the two negatives Eq 3 61 would change to VBC E2 Ir and we will get 2 CO
