1. LF: RE: Question about ground impedance at 8.97 KHZ Stefan. (score: 1): Author: Rik Strobbe <[email protected]>; Date: Fri, 26 Mar 2010 21:35:34 +0100; Paul, I believe that Marcus reported a loss resistance ("ground loss") of about 1 kOhm. For Stefan: based on 250W/0.48A the total loss resistance should be 1085 Ohm. The coil (553mH, Q=82) counts for; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00161.html (13,227 bytes)

(score: 1): Author: Stefan Schäfer <[email protected]>; Date: Sat, 27 Mar 2010 00:46:25 +0100; Sri, i have to correct that: If taking my 553mH and a Q of 82 one arrives at R = 380 Ohm. I mentioned a R of abt 300 Ohm but this is the DC resistance. The difference might be due to the proximity ef; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00595.html (14,268 bytes)
