    A tetrahedral is consisting of 6 identical wires as shown in the figure. Each wire is having a resistance of \[4\Omega .\] When an ideal cell of emf \[5\,V\]is connected across AB as shown, then current through OR is

    A)  4A              

    B)  \[\frac{6}{19}A\]

    C)  zero               

    D)  1 A

    Correct Answer: C

    Solution :

     From the symmetry of the figure, it is clear that O and R are at same potential so no current flows from OR branch. Thus, \[{{I}_{OR}}=0\](zero).
