Default A small riddle, just for fun

Hello Tony,

Jimmie, that is not the point.


At some frequency, everything becomes a distributed component, it
depends on size/lambda ratio and application. Many distributed
components can be modelled based on theoretical lumped components
(with sufficient accuracy), but a ground for modelling stray
capacitance is frequently required.

True lumped component behaviour, in my opinion, only applies to
networks with size=0.

- if the bipole is made of lumped components, then it can be freely reversed
without consequences, independently of whether it is symmetrical or
asymmetrical


What do you define as "lumped component"?

- a trap, which instead contains a distributed element (that is the radiating
trap body), can be freely reversed without consequences only if it is
symmetrical (which is not my case).


I agree on the above.
