Vedclass · Answer

(C) To obtain the lowest equivalent resistance,all resistors must be connected in parallel.The formula for equivalent resistance $R_{eq}$ of $n$ resistors each of resistance $r$ connected in parallel is given by:$\frac{1}{R_{eq}} = \frac{1}{r} + \frac{1}{r} + ... + \frac{1}{r}$ ($n$ times)$\frac{1}{R_{eq}} = \frac{n}{r}$Given:Number of resistors $n = 10$Resistance of each resistor $r = 1/10\,\Omega = 0.1\,\Omega$Substituting the values:$\frac{1}{R_{eq}} = \frac{10}{0.1} = 100$$R_{eq} = \frac{1}{100}\,\Omega$

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