Physics - Current Electricity Question with Solution | TestHub

When all the resistors are connected in series, the total resistance is

$R_{max}=10R$

$\Rightarrow R_{max}=10\times 10=100\Omega$

When all the resistors are connected in parallel, the total resistance is

$R_{min}=\frac{R}{10}$

$\Rightarrow R_{min}=\frac{10}{10}=1\Omega$

Hence, the ratio,

$\frac{R_{max}}{R_{min}}=\frac{100\Omega }{1\Omega }=100$.
