An infinite sequence of resistance is shown in the figure. The resultant resistance between A and B will be, when R1 = 1 ohm and R2 = 2 ohm
(2) 1 Ω
(3) 2 Ω
(4) 1.5 Ω
(3) Let the resultant resistance be R. If we add one more branch, then the resultant resistance would be the same because this is an infinite sequence.
