Wheatstone bridge ?
1. The problem statement, all variables and given/known data
Will the balancing condition get modified in Wheatstone bridge if AC source is used instead of a battery ?
2. Relevant equations
3. The attempt at a solution

No, but if you use a galvanometer (as is usual) as a detector, it wouldn't move.
You would need an AC meter, which probably woudn't be as sensitive as a galvanometer.

In fact, instruments are made that are AC bridges. Select a frequency, amplitude and the spieces of impedence, inductance, ESR and so forth, that you want numbers for, and they display the effective values.
