Question

A combination consists of three resistors in series. Four similar sets are connected in parallel. If the resistance of each resistor is $2\Omega$. Find the equivalent resistance of the combination.

Answer 1

$\frac{1}{R_{eq}}=\frac{1}{6}+\frac{1}{6}+\frac{1}{6}+\frac{1}{6}$

$\frac{1}{R_{eq}}=\frac{4}{6}$

$R_{eq}=\frac{3}{2}=1.5\Omega$
