Three resistors of resistances 11~\Omega, 22~\Omega and 33~\Omega are connected in parallel. Their equivalent resistance is equal to

Explanation

For resistors in parallel, \frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}. Here, \frac{1}{11} + \frac{1}{22} + \frac{1}{33} = \frac{6}{66} + \frac{3}{66} + \frac{2}{66} = \frac{11}{66} = \frac{1}{6}. Thus, R_{eq} = 6~\Omega.
