To what value must you adjust $R_{3}$ to balance a Wheatstone bridge, if the unknown resistance $R_{\mathrm{x}}$ is $100 \Omega, R_{1}$ is $50.0 \Omega,$ and $R_{2}$ is 175$\Omega$ ?

28$\cdot 57 \Omega$

So in this problem, we are. So we have the wisdom bridge and for the wisdom reached, we have a very famous result. So our ex are one they call our two or three to get embarrassed, right? So we can get our three equal r x r one divide by aren't too. And you have the value off this three resistance in the problem. So we can just plug into this values and to say that final solution for our three is 28.6 homes, okay?
