? There is no exact means of tank calculating circulating current
because the voltage at the Tune-C and Load-C is somewhat dependant on
operator adjustment. A fair approximation is tank Q multiplied by anode
current.
I have always used the above formula to determine the proper wire/tubing
size when designing tank coils. I have never had a coil get hot; so far, so
good!
