The lowest resistance which can be obtained by connecting 10 resistors each of 1/10 ohm is

Lowest resistance will be in the case when all the resistors are connected in parallel.

$\begin{array}{l}\frac{1}{\mathrm{R}}=\frac{1}{0.1}+\frac{1}{0.1}....10\mathrm{times}\\ \frac{1}{\mathrm{R}}=10+10......10\mathrm{times}\\ \frac{1}{\mathrm{R}}=100\mathrm{or}\mathrm{R}=\frac{1}{100}\mathrm{\Omega }\end{array}$
