hi, for a wheatstone bridge with 5V input connected to 2 op-amp of gain= 20, gain=30.how much is the voltage output(Vo)? appreciate all help, thanks

 

It could be anything You need to provide schematics with values if you want help.

 

You will have to account for the voltage drops for the diodes, and then you can calculate the gain boosts.

But, t06afre is correct, it really depends how its wired.
