In a battery of 10 cell supposed to be in series some are wrongly connected. The cells are sealed in a box. When a similar cell is connected in opposition to the battery, the current produced by the combination through an external resistor of `14.5Omega` is 0.075 A. How many cells are wrongly connected? What is the emf of the battery and what is its internal resistance if emf of each cell is 1.5V and internal resistance `0.5Omega`?
