Hello,
I have a question for the group. I have Jim Hawkins Pi network
calculator and the numbers the program are producing in the Inductor
calculator is not making complete sense to me. I need a little
clarification please.
If I enter a Dia. of 3? and a Length of 3? into the calculator blank
field, I get an approximation of 3 turns for the Coil and approximately
1? Spacing between each turn. My question is that if that?s correct
then why if I add the wire/tubing dia. In inches plus (+) the 1?
spacing, the overall length is now longer then the 3? length that I
originally entered in as the Length?
If I am using ½ tubing with 1? spacing then the overall length is now
5?. From beginning to end of coil in order to make up 3 turns, I have 2
complete turns with 2 half turns at each end of the coil. So I have 2?
in total tube material plus 3? inches of total spacing. Together I have
an over all length of 5? now vs. the 3? length that I originally called
out for?
I hope what I wrote makes sense if not I can try and elaborate.
One again thanks for the help!
Chris
