A wire having resistance 12Ω is bent in the form of an equilateral triangle. The effective resistance between any two corners of the triangle will be
Options
(a) 6Ω
(b) 8/3Ω
(c) 9Ω
(d) 12Ω
Correct Answer:
8/3Ω
Explanation:
As resistance, R ∝ length
.·. Resistance of each arm = 12 / 3 = 4 Ω
So, effective resistance between any two corners,
Reff = (4×8) / (4+8) = 32 / 12 = (8/3) Ω
