WebIn this case we can assume that the internal resistances are zero. So, we can simply apply the Kirchoff Voltage Law in the loop. V eff = E 1 - E 2. (Given r 1 = r 2 = 0) Given the EMF of one cell is E 1 = 1.25 V. The EMF of the other cell is E 2 = 0.75 V. V eff = E 1 - E 2 = 1.25 V - 0.75 V = 0.5V. So, the correct option is 0.5 V.
