Hi guys, I'm totally confused how do we treat the "air" between two circuits, I meanlets assume I have two circuits connected as two stages, but sometimes lets assume the second stage is in cut off, (there's a disconnect in its component which there will not be current pass to the second stage ! ) my question is, when I want to calculate the input resistance in the first stage, when I don't include the resistances from the second stage?
to be more clearlets assume I have "circuit" like this: STAGE 1 totally "Air " STAGE 2I want to calculate the input resistance of the "circuit", then we just calculate the input resistance of STAGE1 and not including the second stage, why? is it because "Air" if so? then why! I'm not understanding how "Air" is preventing me to complete my calculation to the consecutive Stage !
"Air" I know it's like cut off, but how I can include it through my analysis? why at "AIR" we stop calculation and not complete?!
