Question

The circuit diagram shown consist of a large number of elements (each element has two resistors R₁ and R₂). The resistances of the resistors in each subsequent element differs by a factor of k = 1/2 from the resistances of the resistors in the previous elements. The equivalent resistance between A and B shown in figure is

Answer 1

Correct option: (c) 

Explanation: 

When each element of circuit is multiplied by a factor k then equivalent resistance also become k times. 

Let the equivalent resistance between A and B be X
