Three 3ω resistance are connected in parallel what is the equivalent resistance?

Three 3ω resistance are connected in parallel what is the equivalent resistance?

Correct Answer: Option A

Explanation

Resistor connected in a parallel have an equivalence given by
(frac{1}{text{Reff}}) = (frac{1}{3}) + (frac{1}{3}) + (frac{1}{3})
= (frac{1 + 1 + 1}{3}) = (frac{3}{3}) = 1
Reff = 1ω
