Armature Resistance of Series DC Generator given Output Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Armature Resistance = (Converted Power-Output Power)/(Armature Current^2)
R_a = (P_conv-P_out)/(I_a^2)
This formula uses 4 Variables

Variables Used

Armature Resistance - (Measured in Ohm) - Armature Resistance is the ohmic resistance of the copper winding wires plus the brush resistance in an electrical generator.
Converted Power - (Measured in Watt) - Converted Power refers to the electrical power output that is generated by the conversion of mechanical energy into electrical energy.
Output Power - (Measured in Watt) - Output Power refers to the product of current and voltage at the output terminal of a dc generator.
Armature Current - (Measured in Ampere) - Armature Current is defined as the current developed in the armature of an electrical DC generator due to movement of rotor.

STEP 1: Convert Input(s) to Base Unit

Converted Power: 165.5 Watt --> 165.5 Watt No Conversion Required
Output Power: 150 Watt --> 150 Watt No Conversion Required
Armature Current: 0.66 Ampere --> 0.66 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_a = (P_conv-P_out)/(I_a^2) --> (165.5-150)/(0.66^2)

Evaluating ... ...

R_a = 35.5831037649219

STEP 3: Convert Result to Output's Unit

35.5831037649219 Ohm --> No Conversion Required

FINAL ANSWER

35.5831037649219 ≈ 35.5831 Ohm <-- Armature Resistance
