Question

Three resistors are connected to form the sides of a triangle ABC, the resistance of the sides AB, BC and CA are 40 ohms, 60 ohms and 100 ohms respectively. The effective resistance between the points A and B in ohms will be [JIPMER 2002]
A) 32 B) 64 C) 50 D) 200

Answer 1

Heya !!!

here is your answer :-


here your answer is 32


hope it's helped !!

Answer 2

hello friend...!!

firstly, according to the question's given condition

40ohm and 60 ohm are series so,

R = R(ac) + R (cb)

R = 100 + 60

R = 160 ohm ------------( 1 )

this R is parallel to 40 ohm,

therefore,

1 / R = 1 / 40 + 1 / 160

1 / R = 5 / 160

R = 160/5

R = 32 ohm.

Therefore, the answer is option A

hope it helps...!!!
