In Reply to: RE: If the signal goes in both caps they must divide. posted by Tre' on April 12, 2017 at 13:36:02
But this, I think, is a case where the water analogy falls apart. I don't think you could in theory put your finger on one electron and say that this one went through capacitor A and that one went through capacitor B. All the signal goes through both capacitors, is how I think of it. In fact, one might support that position by the observation that the capacitors in parallel provide a net additive capacitance across the whole signal. Somehow, the signal is in both capacitors at once.

"I don't think you could in theory put your finger on one electron and say that this one went through capacitor A and that one went through capacitor B."
And just to add another bit of fun to the discussion, electrons don't actually pass through the capacitor at all; that is to say they don't cross between the plates of the capacitor.

but I couldn't think of a better "unit of audio signal".
"but I couldn't think of a better "unit of audio signal"."
I know, and it was really just pure pedantry, but I couldn't resist!
Think of 2 resistors in parallel.Capacitors have reactance so that at any given frequency each cap has a reactance value.
The two caps in parallel will have one half of that reactance value just like 2 (equal value) resistors in parallel will have one half the value of one.
I don't see the water analogy falling apart but yes, the signal is in both capacitors at once but one cap is carrying half the current and the other cap is carrying the other half of the current.

Can't know both position of particle (electron) and momentum (energy, frequency), at the same time.Some dude name Heisenberg figured that out in the 1920s.

While we may not be able to pin down individual electrons, statistically, the net effects are quite predictable.
