n identical cells, each of emf e and internal resistance r, are first connected in series and then in parallel. What will be the ratio of the emfs and of the internal resistances of these two cell combinations?

n-identical cells each of emf E and internal resistance r are connected in series. Find the expression for current in the circuit given below

n-identical cells each of emf E and internal resistance r are connected in series. Find the expression for current in the circuit given below.

7 cells each of emf epsilon and internal resistance r are to be connected in series. If due to oversight one cell is connected wrongly, the emf and internal resistance of the combination will be :

Six cell each of emf E and internal resistance r are connected in series. If due to over sight, two cells are connected wrongly, then the equivalent emf and internal resistance of the combination is

Four identical cells of emf e and internal resistance r are to be connected in series. Suppose, if one of the cell is connected wrongly, the equivalent emf and effective internal resistance of the combination is:

Four identical cells of emf E and and internal resistance r are to be connected in series . Suppose if one of the cell is connected wrongly , the equivalent emf and effective internal resistance of the combination is

A cell of emf E and internal resistance r is connected in series with an external resistance nr. Than what will be the ratio of the terminal potential difference to emf, if n=9.
