Change in Q due to temperature changes
Original poster: "Jim Lux by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jimlux-at-earthlink-dot-net>
The temperature coefficient of Copper is approximately 0.0043/degree.. A 20
degree (C) change will result in an 8-9% change in DC resistance. Since Q
is X/R, Q will change in the same proportion.
Skin depth varies as 1/sqrt(conductivity) or sqrt(resistivity), so the skin
depth gets bigger as the resistance rises... This will tend to counteract
the rising resistance...
