Q. Three resistances each of $4\Omega$ are connected in the form of an equilateral triangle. The effective resistance between any two corners is
A) $(3/8)\ \Omega$
B) $(8/3)\ \Omega$
C) $8\ \Omega$
D) $12\ \Omega$
Explanation
(b) The equivalent resistance between two corners of equilateral triangle having resistance $R$ in each arm $= 2R/3 = 2 \times 4/3\ = 8/3\Omega$
