Half Scale Resistance for Series Type Ohmmeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Half Scale Resistance = (Voltage Source*Zero Adjusting Resistance)/(Current Full Scale Reading*Zero Adjusting Resistance+Current Full Scale Reading*Meter Resistance)
R_h = (E*R₂)/(I_f*R₂+I_f*R_m)
This formula uses 5 Variables

Variables Used

Half Scale Resistance - (Measured in Ohm) - Half Scale Resistance refers to the resistance value halfway between the maximum and minimum resistance of a variable resistor or potentiometer, typically used to calibrate or set reference points.
Voltage Source - (Measured in Volt) - Voltage Source refers to as a fundamental element that supplies electrical energy to a circuit.
Zero Adjusting Resistance - (Measured in Ohm) - Zero Adjusting Resistance refers to a variable resistor used to calibrate or adjust the zero reading of a measuring instrument.
Current Full Scale Reading - (Measured in Ampere) - Current Full Scale Reading represents the maximum current that the ohmmeter will pass through the resistor when it's being measured at its highest resistance value.
Meter Resistance - (Measured in Ohm) - Meter Resistance refers to the internal resistance of a measuring instrument. This resistance is inherent to the design of the instrument and affects the accuracy of measurements made by the device.

STEP 1: Convert Input(s) to Base Unit

Voltage Source: 15.5 Volt --> 15.5 Volt No Conversion Required
Zero Adjusting Resistance: 36 Ohm --> 36 Ohm No Conversion Required
Current Full Scale Reading: 0.2 Ampere --> 0.2 Ampere No Conversion Required
Meter Resistance: 75 Ohm --> 75 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_h = (E*R₂)/(I_f*R₂+I_f*R_m) --> (15.5*36)/(0.2*36+0.2*75)

Evaluating ... ...

R_h = 25.1351351351351

STEP 3: Convert Result to Output's Unit

25.1351351351351 Ohm --> No Conversion Required

FINAL ANSWER

25.1351351351351 ≈ 25.13514 Ohm <-- Half Scale Resistance
