Question

solve a

a) Using the circuit in the figure, the experimenter RA R1 R2 calculates the internal resistance Rx of the structure "X" as A "U/I" (U and I: Readings of the instruments). Express the method error (either absolute or relative) in this calculation in terms of given. Rx V R3 Ry b) The resistance R of a resistor is determined as "R=U/l". Here, U is calculated from the reading of a V- meter (nominal voltage: Un, class: 0.5) observing a deflection of 1/3 rd of the full scale. Similarly, I is calculated by observing half-scale deflection on an A-m. What is the class of the A-m if the highest possible value for the instrumental error in resistance calculation is found as 2.5% ? (Give sufficient detail of your calculation)
