Q. Three resistors are connected to form the sides of a triangle $ABC,$ the resistance of the sides $AB,\ BC$ and $CA$ are $40\ ohm,\ 60\ ohm$ and $100\ ohm$ respectively. The effective resistance between the points $A$ and $B$ in $ohm$ will be

A) 32
B) 64
C) 50
D) 200
Explanation

(a) $R = \frac{160 \times 40}{160 + 40} = 32\Omega$
