Meter Current for Shunt Type Ohmmeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Meter Current = (Voltage Source Shunt*Unknown Shunt Resistance)/(Shunt Resistance*Resistance of Shunt Meter+Unknown Shunt Resistance*Shunt Resistance+Unknown Shunt Resistance*Resistance of Shunt Meter)
I_meter = (E₁*R_x1)/(R_s1*R_m1+R_x1*R_s1+R_x1*R_m1)
This formula uses 5 Variables

Variables Used

Meter Current - (Measured in Ampere) - Meter Current is the current flowing through the coil of an ohmmeter when in working state.
Voltage Source Shunt - (Measured in Volt) - Voltage Source Shunt is the value of the voltage applied in the shunt ohmmeter.
Unknown Shunt Resistance - (Measured in Ohm) - Unknown Shunt Resistance is the value of the unknown resistance connected for measurement.
Shunt Resistance - (Measured in Ohm) - Shunt Resistance is the current limiting resistance in an ohmmeter.
Resistance of Shunt Meter - (Measured in Ohm) - Resistance of Shunt Meter is an instrument resistance.

STEP 1: Convert Input(s) to Base Unit

Voltage Source Shunt: 1.5 Volt --> 1.5 Volt No Conversion Required
Unknown Shunt Resistance: 30 Ohm --> 30 Ohm No Conversion Required
Shunt Resistance: 0.8695 Ohm --> 0.8695 Ohm No Conversion Required
Resistance of Shunt Meter: 1.25 Ohm --> 1.25 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_meter = (E₁*R_x1)/(R_s1*R_m1+R_x1*R_s1+R_x1*R_m1) --> (1.5*30)/(0.8695*1.25+30*0.8695+30*1.25)

Evaluating ... ...

I_meter = 0.695820246436337

STEP 3: Convert Result to Output's Unit

0.695820246436337 Ampere --> No Conversion Required

FINAL ANSWER

0.695820246436337 ≈ 0.69582 Ampere <-- Meter Current
