1.	A modified Wheatstone bridge is used to measure the value of load resistance RL shown in figure. The resistance RX is varied such that balance is obtained, then value of branch parameters are as followsRa=140Ω; Rb=0.75Ω;R1=70Ω; R2=180Ω;R3=0.375Ω Determine the value of RX
Answer» A modified Wheatstone bridge is used to measure the value of load resistance $R_{L}$ shown in figure. The resistance $R_{X}$ is varied such that balance is obtained, then value of branch parameters are as follows $R_{a} = 140 Ω;$ $R_{b} = 0.75 Ω;$ $R_{1} = 70 Ω;$ $R_{2} = 180 Ω;$ $R_{3} = 0.375 Ω$ Determine the value of $R_{X}$
