Re: Multiple toroid capacity
Original poster: "Dr. Resonance by way of Terry Fritz <teslalist-at-qwest-dot-net>" <resonance-at-jvlnet-dot-com>
Due to the "shielding effect" when multiple toroids are used the value is
always less than the value of two separated individual toroids added
together. With two toroids a rule of thumb is you deduct from the total
separate added capacitance approx. 50% of the value of a single toroid's
capacitance. This will give you a good ballpark figure assuming both
toroids have the same physical size.
If the sizes are different then it's usually easy just to measure the total
with a Wavetek or equiv. meter.
