Question

Equivalent resistance between A and B in a triangle

Answer 1

Explanation:

Resistance along path 2 (A-->B-->C) = 2+2 = 4 ohm, as both the 2 ohm resistors are in a series connection. Now both these paths are in parallel (any two paths are in parallel when both their end points are the same, or at the same potential). So, we have the final resistance between A and C..
