Hello group, many thanks to all who replied on my request.One more thought : if the loop would be very good (= low loss, let's say about 0.5 Ohm) this would mean high current and thus also rather high voltage (as Jim mentioned). The loop would have an inductance of about 120uH (thus XL = 100 Ohm), so pumping 450W into the loop would give a current of 30A and a voltage of 3kV. Isn't it likely that these high voltages will cause some additional losses (there will be some current floating to ground) ? 73, Rik ON7YD |
