Question
The ac bridge in Fig. 9.37 is balanced when $R_{1}=400 \Omega, R_{2}=600 \Omega, R_{3}=1.2 \mathrm{k} \Omega,$ and$C_{2}=0.3 \mu \mathrm{F} .$ Find $R_{x}$ and $C_{x}$
Step 1
In this case, we have $Z_{1}=R_{1}$, $Z_{2}=R_{2}+1/j\omega C_{2}$, $Z_{3}=R_{3}$, and $Z_{4}=R_{x}+1/j\omega C_{x}$. 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 $\frac{R_{2}}{R_{1}}=0.625$ $?$
In a Wheatstone's network, $P=2 \Omega ; Q=2 \Omega ; R=2 \Omega$ and $S=3 \Omega$. the resistance with which $S$ is to be shunted in order that the bridge may be balanced is (a) $1 \Omega$ (b) $2 \Omega$ (c) $4 \Omega$ (d) $6 \Omega$
In the whetstone bridge shown below, in order to balance the bridge we must have (A) $R_{1}=3 \Omega, R_{2}=3 \Omega$ (B) $\mathrm{R}_{1}=6 \Omega, \mathrm{R}_{2}=15 \Omega$ (C) $\mathrm{R}_{1}=1.5 \Omega, \mathrm{R}_{2}=$ any finite value (D) $\mathrm{R}_{1}=3 \Omega, \mathrm{R}_{2}=$ any finite value
