Re: [TCML] Inductor design program?

[jhowson4@xxxxxxxxxxx]

I see, 
so I can use the slope to obtain XL 
which is equal to 2*pi*60*L 
which can be used in the ohms law equation like this? 

V/( I*2*pi*f)=L 
so (140 V) / (30 A * 120*pi) =12.4mH ? 

which seems wrong to me because I have always seen mention of 100mH inductors being used? 

Thanks, 
Jay 



take it I would be graphing Voltage vrs Current? and the slope is inductance? 
r is it Current Vrs Voltage. 
Thanks,

Hi Jay, 
The slope is neither. 
It's Inductive reactance, XL = E/I (ohms = volts/amps) 
Inductance, L = XL/(2pi*f) 
Some folks who work exclusively in the 60 Hz world 
use the terms interchangably, since for them the 
term 2pi*f is only a constant, but they're not the same quantity. 
Hope this helps, 
Matt D
