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 $\frac{R_{2}}{R_{1}}=0.625$ $?$

So with Stonebridge consists off for a mistress in quadrilateral. On Dhe there is ah, current sensing device and we want with stone rich balanced so that this current here is zero i j zeros potential is applied between these two points. This is are too. I won on DDE. This will be our X. This must be on three. So for the balanced equation, we know that our it's is equal to are truly wanted by on one times on three. So our X will be by in 6 to 5 times 2500. Because that's the value of to our three. Okay, so this multiplication will yield 5 1026 5 62 I'm sorry about that. 0.5 or so. If X is exactly equal to this, this bridge is balanced on. There is no current flowing between this and this point because these two points will have equal potential. Thank you.
