Homework Statement
A 4 pole lap wound armature has 16 coils, each with a resistance of 0.1 ohms. Calculate the resistance of the armature?
Homework Equations
The Attempt at a Solution
Hi there fellow members,
I'm currently doing a section of my course which deals with Electrical machines. The lesson that I am on at the moment is dealing with Armature windings ( lap and wave ).
There are two diagrams in the lesson but they are confusing.
One leads me to think that the total resistance would be 16*.01 ='s 1.6 ohms
The other one leads me to think that there are 4 parallel paths. 4*4 = 16
4*0.1=0.4 so total resistance is
1/R = (1/0.4)*4
R = 1/10
R = 0.1 ohms
With the fact that it's a question being asked I would think that the 1.6 is a bit straight forward so I'm leaning towards the 0.1 ohms answer.
Any help/suggestions would be greatly appreciated :)
Neil
P.S Thanks for taking the time to read the question!
