Armature Resistance of Shunt DC Motor given Voltage Solution

STEP 0: Pre-Calculation Summary

Formula Used

Armature Resistance = (Supply Voltage-Back EMF)/Armature Current
R_a = (V_sp-E_b)/I_a
This formula uses 4 Variables

Variables Used

Armature Resistance - (Measured in Ohm) - The Armature Resistance is the ohmic resistance of the copper winding wires plus the brush resistance in an electrical dc motor.
Supply Voltage - (Measured in Volt) - Supply Voltage is the input voltage being fed to the dc motor circuit. Supply voltage refers to the electrical voltage provided to an electrical device or system, such as an electric motor.
Back EMF - (Measured in Volt) - The Back emf opposes the current which causes it in any dc machine. Back emf refers to the voltage that is generated in an inductor or a coil of wire when the current flowing through it changes.
Armature Current - (Measured in Ampere) - Armature Current DC motor is defined as the armature current developed in an electrical dc motor due to the rotation of rotor.

STEP 1: Convert Input(s) to Base Unit

Supply Voltage: 239 Volt --> 239 Volt No Conversion Required
