Q. 25. A tattery of emt 3 V and internal resistance 111 is connected m
parallel with a cell of emf 1.5 V and internal resistance 0,50 with
their like poles together. The combination is used to pass a current
through a resistor of resistance of 50. Using Kirchhoff's circuital
laws, find the current through the 50 resistor.
