A Wheatstone bridge of the type shown in Figure $28.25$ is used to make a precise measurement of the resistance of a wire connector. If $R_{3}=1.00 \mathrm{k} \Omega$ and the bridge is balanced by adjusting $R_{1}$ such that $R_{1}=2.50 R_{2}$, what is $R_{x} ?$

Step 1
Step 1: From the Wheatstone bridge equation, we have the ratio of resistances as $R_1/R_2 = R_3/R_x$. Show more…

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 $\frac{R_{2}}{R_{1}}=0.625$ $?$
(Wheatstone bridge) Show that if $R_{x} / R_{3}=R_{1} / R_{2}$ in the figure, then $I=0 .(R_{0}$ is the resistance of the . instrument by which $I$ is measured.) This bridge is a method for determining $R_{x^{\prime}} . R_{1}, R_{0}, R_{3}$ are known. $R_{3}$ is variable. To get $R_{n}$ make $I=0$ by varing $R_{3}$ Then calculate $R_{B}=R_{2} R_{1} / R_{2}$.

An unknown length of platinum wire 1.22 $\mathrm{mm}$ in diameter is placed as the unknown resistance in a Wheatstone bridge (see Problem $71,$ Fig. $65 ) .$ Arms 1 and 2 have resistance of 38.0$\Omega$ and $29.2 \Omega,$ respectively. Balance is achieved when $R_{3}$ is 3.48$\Omega .$ How long is the platinum wire?
