Diodes in Electric Circuit

    Hi;

    Consider this circuit (ignore my bad drawing):

    In the picture there is one cell, two diodes and a bulb. Will the current get trapped in the second branch and continuously flow around that loop?

    Thanks.

    According to Kirchhoff's loop rule,applied to the loop on the right, the potential difference across the bulb must be 0, so no current can flow through it.

    Well, no current will flow anyway because of the fact that the two diodes are facing eachother and you have indicated a DC source.
