(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A bridge initially has resistances equal to R1=100ohms, R2= 200ohms, R3= 250ohms, R4= 300ohms. Determine output voltage at this condition for an input voltage of 3V. What is the bridge output if R1 changes to 125ohms?

2. Relevant equations

Havent been given any. I am assuming something to do withOhms Law?

3. The attempt at a solution

I used Ohms Law. But I dont know if I am on the right track.

I= E/ R

I= 3/ 850 = 0.00353 amps.

Now I dont know what to do. Or if I was even supposed to use this Law.

Any help would be much appreciated :) Thanks alot.
