Value of Rh for Series Type Ohmmeter Solution

STEP 0: Pre-Calculation Summary
Formula Used
rh_s = Voltage*Resistance 2/(Current (fs)*Resistance 2+Current (fs)*Rm)
Rh = E*R2/(Ifs*R2+Ifs*Rₘ)
This formula uses 4 Variables
Variables Used
Voltage - Voltage is the value of the voltage applied in the ohmmeter. (Measured in Volt)
Resistance 2 - Resistance 2 is the zero adjust or shunt resistance of the ohmmeter (Measured in Ohm)
Current (fs) - Current (fs) is the measure of the full scale current flowing through the meter (Measured in Ampere)
Rm - Rm is the internal resistance of the coil in PMMC instrument (Measured in Ohm)
STEP 1: Convert Input(s) to Base Unit
