The n rows, each containing m cells in series are joined in parallel. From this combination across an external resistance of `6Omega`, maximum current is taken. Let the total number of cells used be 6 and internal resistance of each cell be `1Omega`, then the value of `m+n` is,

Text Solution

Verified by Experts

The correct Answer is:
`07.00`
Total no: of cells `= m xx n = 6` ... (i)
For maximum current in the circuit, `R=(mr)/(n)`
`:. 6 = (m)/(n) xx (1) rArr m = 6n` ....(ii)
On solving equations (i) and (ii),
m = 6, n=1
`:.m+n =6+1=7`
