The resultant resistance value of three resistors each of

r ~\Omega

are connected in series is

x

. When given three resistances are connected in parallel, the resultant value is

View answer and explanation

Correct option: B

\frac{x}{9}

Option B (x/9) is correct because when three resistors of r are connected in series, the total resistance is 3r=x, so r=x/3. In parallel, the equivalent resistance is r/3 = x/9.
