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
