Equivalent resistance between A and B will be

1. 2 ohm
2. 18 ohm
3. 6 ohm
4. 3.6 ohm

Correct answer: 3.6 ohm

Solution

The equivalent resistance is obtained by successive simplification of the given resistor network. After combining the appropriate series and parallel parts, the net resistance between A and B comes out to be 3.6 ohm.
