3-29 A series ohmmeter is made up of the following components: supply voltage \( E_{B}=3 \) \( \mathrm{V} \), series resistor \( R_{1}=30 \mathrm{k} \Omega \), meter shunt resistor \( R_{2}=50 \Omega \), meter \( \mathrm{FSD}=50 \mu \mathrm{A} \), and meter resistance \( R_{m}=50 \Omega \). Determine the resistance measured at \( 0,0.25,0.5 \), and \( 0.75 \) of full-scale deflection. Q-2-part b: 3-31 For the ohmmeter circuit in Problem 3-29, determine the new resistance to which \( R_{2} \) must be adjusted when \( E_{B} \) falls to \( 2.5 \mathrm{~V} \).
