Question
Three resistances each of 4 Ohm are connected in the form of an equilateral triangle. The effective resistance between any two corners is:
Options:
A .  38 Ohm
B .  83 Ohm
C .  8 Ohm
D .  12 Ohm
Answer: Option B
:
B
Two in series = 8 Ohm
This 8 Ohm will be parallel to 4 Ohm which gives a resultant =(4×84+8)=(83)Ohm.
