To get maximum current through a resistance of $2.5\Omega$, one can use $‘m’ $ rows of cells, each containing $‘n’$ cells connected in series. The internal resistance of each cell is $0.5\Omega$. What are the values of $ n$ and $m$ if the total numbers of cells are $45$? - Clay6.com, a Free resource for your JEE, AIPMT and Board Exam preparation
