Answer:
The answer will be 8E and 10 r
Explanation:
According to the problem there are 10 dry cell of emf E
Therefore the net emf of this system is 10E
As the student connect one cell wrong therefore this cell will not cancel the another cells
Therefore the number of equivalence cell is 8E
Now the internal resistance of all the cells are connected in series as the problem stated except the one cell which is connected wrongly
The net resistance will be 10r
