In the shown wire frame, each side of a square (the smallest square) has a resistance R. The equivalent resistance of the circuit between the points A and B is –
A
R
B
2R
C
4R
D
8R
Answer
2R
Explanation
Solution
The circuit can be folded about B and redrawn as
≡ 
Hence equivalent resistance between A and B is 2R.
