The ratio of maximum to minimum resistance of 'n' resistors each of resistance R is given by:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $n^2$
Case I: When all n-resistor are connected in series
$R_{series}=r+r+r+....(n\,times)$
$=rn$ [Series]
Case I: When all n-resistor are connected in parallel
$R_{parallel}=\frac{r}{n}$
$∴\frac{R_{series}}{R_{parallel}}=\frac{rn}{\frac{r}{n}}=n^2$
