Current through coils
Richard Clark wrote:
"The apparent capacitance based on reported resonances and modeled reactance is on the order of 12 -14 pF." Have you calculated the self-capacitance of a 2in x 12in single-layer coil for yourself? The length to diameter ratio is 6. H = .92 D = 5 cm HD = 4.6 pF by the formula on page 451 of the "Radiotron Designer`s Handbook". Course, formulas are a dime a dozen and disputed.
