# Solve this: 80. There are 32 cells each having emf 1 V and internal resistance 1 $\Omega$. All the cells are connected together in a closed loop. When terminal voltage of cells are measured, they are found to be either 0.5V or 1.5 V. How many cells are having their polarities reserved with respect to the majority of cells? (1) 6              (2) 12 (3) 8              (4) 10
