Armature Copper Loss Solution

STEP 0: Pre-Calculation Summary
Formula Used
armature_loss = Armature Current*Armature Current*Armature resistance
Pa = Ia*Ia*Ra
This formula uses 2 Variables
Variables Used
Armature Current - Armature Current is the Current which Flows in Armature Winding or rotating Winding of Motor or generator. (Measured in Ampere)
Armature resistance - The Armature resistance is given is the opposition that a substance offers to the flow of electric current. (Measured in Ohm)
STEP 1: Convert Input(s) to Base Unit
Armature Current: 0.5 Ampere --> 0.5 Ampere No Conversion Required
Armature resistance: 3 Ohm --> 3 Ohm No Conversion Required
STEP 2: Evaluate Formula
