A battery is made by joining m rows of identical cells in parallel. Each row consists of n cells joined in series. This battery sends a maximum current I in a given external resistor. Now the cells are so arranged that instead of m rows, n rows are joined in parallel and each row consists of m cells joined in series. Find the current through the same external resistor (Total number of cells which is equal to NM is connected).

1.	A battery is made by joining m rows of identical cells in parallel. Each row consists of n cells joined in series. This battery sends a maximum current I in a given external resistor. Now the cells are so arranged that instead of m rows, n rows are joined in parallel and each row consists of m cells joined in series. Find the current through the same external resistor (Total number of cells which is equal to NM is connected).
Answer» Each row CONSISTS of n cells joined in series. The total number of cells is EQUAL to N. This battery SENDS a maximum current LIN a given external circuit. Now, the cells are so ARRANGED in the battery that instead of m rows rows are joined in parallel and each row consists of m cells joined in series.
