## Homework Statement

Find the detector current i_d in the unbalanced bridge in the figure if the voltage drop across the detector is negligible. The source voltage v_g is 180V.

## Homework Equations

## The Attempt at a Solution

I am not sure what to do, or even how to find the equivalent resistance. I have learned the delta-y transformation, but I don't suspect that will help me here, since the detector has negligible resistance, right? (and if it doesn't have negligible resistance, than the current is negligible, if i am understanding V=IR correctly)

Someone to point me in the right direction would be greatly appreciated.
