1. The problem statement, all variables and given/known data Suppose that in the course of a measurement the bridge is balanced and then the power supply voltage changes by 10%, what will happen to the balance of the bridge? Explain. 2. Relevant equations No equations. 3. The attempt at a solution When I think it out logically, I don't think the balance should be affected. Because if the voltage increases, the values of the resistances will still be balanced. Is this wrong? But then I think if the voltage increases, you have to balance the bridge out again.
