In the shown wireframe, each side of a square (the smallest square) has a resistance 7 Ω . What is the equivalent resistance value (in ohm) of the circuit between the points A and B ?

Correct answer

14

Step-by-step solution

The circuit can be folded about B and redrawn as Hence equivalent resistance between A and B is 2 R = 2 × 7   Ω = 14   Ω .
