Question

find the equivalent resistance across a b for the given circuit ​

Answer 1

Answer:

1 ohm (option A)

Explanation:

If we consider the smaller rectangle, 2Ω and 2Ω are in series

2+2 = 4 Ω which is parallel to 2Ω

solving we get equivalent for small rectangle as 4/3 Ω

now in the big rectangle, 2 and 2Ω are in series again hence 4Ω which is parallel to 4/3Ω

hence using parallel resistance formula, we get 1 Ω as answer

Answer 2

hence dude i think the answer is 1 ohm...hope it will help you
