I came to this question recently and suppose it's true that the secondary's parasitic capacitance does indeed add up with the value of the top load's capacitance, but I really want to hear someone else's thoughts on the topic since perhaps I'm wrong.
Though very small, the value of the capacitance on the secondary (11.97pF by my calculations) is greatly larger than the value of the top load's capacitance (around 2.5pF.)
If what I'm saying is true and these numbers do in fact add to each other when connected, then I'll most likely make another top load with a larger capacitance.
My question is as stated in the title. Does the parasitic capacitance of a secondary coil add with the capacitance of the top load?
Secondary inductance is 1530µH, with a parasitic capacitance of 11.97pF gives me a RF of 1.17Mhz. I know that adding a top load decreases this value, but do I add the value of the coil's capacitance to the top load's capacitance?
