OR(a) 12 cells each having the same e.m.f. are connected in aeries and are kept in aclosed box. Some of the cells are wrongly connected. This battery is connectedin aeries with an ammeter and two cells identical with the others. The currentis 3 ampere when the cells and battery aid each other and is 2 ampere whenthe cells and battery oppose each other. How many 20cells in the battery are wrongly connected?[3+2](6) Calculate the steady state current in the 2 ohm resistorshown in the circuit in the figure. The internal resistance of the battery is negligible​
