Three 3ω resistance are connected in parallel what is the equivalent resistance?
-
A.
1ω
-
B.
9ω
-
C.
3ω
-
D.
0.33ω
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
