Hi Matt,

For 1 meter using 1cm wire diameter, straight  wire inductance 
calculations show 1uH. Change the diameter to 0.1cm with  the same 1 
meter length and I calc'd 1.5uH. So, there must be a mistake in  
Richard's Guide. It is easy to see that as the length to diameter ratio  
increases, the difference in the above diameters become negligible. But  
with shorter lengths, the difference can obviously be a great  concern.

Take care,
Bart






Wow!
 
Does this mean that everyone who used Richard Hull's  CSN Guide  to interpret 
Tesla's notes for the last 13 years has been wrong by a factor of  10 on 
inductance,and NOBODY noticed??
