Question

In the figure, the value of resistors to be connected between C and D so that the resistance of the
entire circuit between A and B does not change with the number of elementary sets used is


(A) R
(B) R( √3 - 1)
(D) 3R
(C) R(√3+1)​

Answer 1

Answer:

i don't know answer it i chose 3r randomly and I have explanation if it is correct

Answer 2

Answer:

Let the resistor to be connected across CD be x. Then the equivalent resistance across EF should be x and also across AB should be x.

Let the resistor to be connected across CD be x. Then the equivalent resistance across EF should be x and also across AB should be x.The equivalent circuit is shown in the figure below.
