Now what's this???



All the wires shown in the figure (red color) have resistance 'R'. The only places where the wires are connected are the vertices of the large hexagon.

Find the resistance between points
1)'A' and 'B'.
2)'A' and 'C'.

    hey sambhav

    in this i am not able to apply perpendicular symmetry, aur along the line wali symmetry ismein lage gi nahin

    how you did this

    Total resistance from A → B = 1 + 1.36 = 2.36 * R

    r/3. all 4 black spots are at equal potentials. so there are total 5 resistances in parallel, 4 with res 2r and one with res r.

    Cool down xxx...If i didn't answer, it meant that I was busy or careless (you'd be too if you had 2 assignments, 2 quizzes, 1 interview and 1 re-minor scheduled in a week).

    I particularly hated the last comment, you sort of crossed a line there..seriously!

    The answer is probably R/3. Shourya had even posted the solution.

    Now scroll back for a question titled "The Kings of S". And then think if there was a need for an answer.
