When two terminals of a cell are directly connected to each other, current I passes through it. If 12 such cell are to be connected in such a mannat I is the maximum current then the combination would b

Options

A. 2 cells in a row and 6 such rows in parallel
B. all 12 cells in series
C. all 12 cells in parallel
D. 4 cells in a row and 3 such rows in parallel

Answer

C

Explanation

Here, we have some finite internal resistance of cells and the case of connecting terminals of battery directly to each other can be taken as a case when internal resistance is much higher than external resistance because external resistance is zero. Parallel combination generates maximum current in such a situation. Thus, option (c) is correct.
