To what value must you adjust $R_3$ to balance a Wheatstone bridge, if the unknown resistance $R_x$ is $125 \ \Omega$, $R_1$ is $50.0 \ \Omega$, and $R_2$ is $155 \ \Omega$? 547.5 $\times \ \Omega$ t

Step 1
In this case, we have: $$\frac{R_x}{R_1} = \frac{R_2}{R_3}$$ We are given $R_x = 125 \ \Omega$, $R_1 = 50.0 \ \Omega$, and $R_2 = 155 \ \Omega$. We need to find $R_3$. Show more…

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$\Omega$ ?

When an unknown resistance $R_{\mathrm{x}}$ is placed in a Wheatstone bridge, it is possible to balance the bridge by adjusting $R_{3}$ to be 2500$\Omega .$ What is $R_{\mathrm{x}}$ if $\frac{R_{2}}{R_{1}}=0.625$ $?$
