Question

The least resistance that one can have from six resistors each of 0.1 ohm resistance is:

• A. 0.167$\Omega$
• B. 0.00167 $\Omega$
• C. 1.67 $\Omega$
• D. 0.0167 $\Omega$

Answer 1

The correct option is D 0.0167 $\Omega$

Least resistance is achieved when all the resistors are connected in parallel.
$\therefore R_{eq}=\frac{R}{6}=\frac{0.1}{6}=0.0167\Omega$
