Armature Current Solution

STEP 0: Pre-Calculation Summary
Formula Used
armature_current = Field Current+Load current
Ia = If+Il
This formula uses 2 Variables
Variables Used
Field Current - The Field current is the current flowing through the windings in the non-moving part of the motor. (Measured in Ampere)
Load current - The load current is the current that the appliance is drawing at that instant. (Measured in Ohm)
STEP 1: Convert Input(s) to Base Unit
Field Current: 7 Ampere --> 7 Ampere No Conversion Required
Load current: 10 Ohm --> 10 Ohm No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ia = If+Il --> 7+10
Evaluating ... ...
Ia = 17
STEP 3: Convert Result to Output's Unit
17 Ampere --> No Conversion Required
FINAL ANSWER
17 Ampere <-- Armature Current
(Calculation completed in 00.016 seconds)

Armature Current Formula

armature_current = Field Current+Load current
Ia = If+Il

What is the main difference between the field current and armature current?

Field Current - Current flows in Field Winding or stationary winding of Motor or generator is called field current. Armature Current - Current Flows in Armature Winding or rotating Winding of Motor or generator is called Armature Current.

How to Calculate Armature Current?

Armature Current calculator uses armature_current = Field Current+Load current to calculate the Armature Current, Armature Current is the Current which Flows in Armature Winding or rotating Winding of Motor or generator. An armature is the component of an electric machine that carries alternating current. The armature windings conduct AC current even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. Armature Current and is denoted by Ia symbol.

How to calculate Armature Current using this online calculator? To use this online calculator for Armature Current, enter Field Current (If) and Load current (Il) and hit the calculate button. Here is how the Armature Current calculation can be explained with given input values -> 17 = 7+10.

FAQ

What is Armature Current?
Armature Current is the Current which Flows in Armature Winding or rotating Winding of Motor or generator. An armature is the component of an electric machine that carries alternating current. The armature windings conduct AC current even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors and is represented as Ia = If+Il or armature_current = Field Current+Load current. The Field current is the current flowing through the windings in the non-moving part of the motor and The load current is the current that the appliance is drawing at that instant.
