Q.
The lowest resistance which can be obtained by connecting 10 resistors each of $1 / 10\,\, ohm$ is
Current Electricity
Solution:
Lowest resistance will be in the case when all the resistors are connected in parallel.
$\frac{1}{R}=\frac{1}{0.1}+\frac{1}{0.1} \ldots 10$ times
$\frac{1}{R}=10+10 \ldots \ldots .10$ times
$\frac{1}{R}=100$ or $R=\frac{1}{100} \Omega$
