    Denote the top node of the bridge by A and the bottom by D. Let the nodes be B (left side) and C (right side) for the cross arm containing the resistance and the diode.

    First of all, I am assuming that the ...

    Solution Summary

    Solution is found by finding an equation for the current through the diode from B to C and then applying KCF at node B and C. These two equations can be solved for the 2 unknowns I and VB.
