short circuit frequency ?

[stivep]

here is little better  explanation what is going on if e.g transmission line is shorted.
you are dealing with number of resonant circuits in that transmission line parallel and series .

Hi everyone. I have a question about short circuit and the AC frequency. does the AC frequency change when the short circuit occurs? if yes how much the frequency changes ?

thanks.

Could you please define what you are short circuiting?  I suspect that you are talking about transformers or mutual coupling between two coils, but without knowing what you are dealing with it is impossible to give an answer.

I did, but you didn't  understand what I wrote.it was  the
Answer for piece of coaxial cable known as transmission line that is shorted open or terminated at the end:

the answer:
No  frequency  will not change.. however it may..create transients.__________________________

In any short circuit :
- if mixing of products or byproducts   of LC reactive components  is not happening than frequency doesn't change.
________________________

think of it as:
1. you need  generating circuit to make generation of the signal
2. you need circuity to  process the signal
3. no matter what you do with this circuit - frequency  of already generated signal doesn't change.
However  we must exclude circuits purposely made by us and intended to change frequency of the signal by means of e.g mixing.
Mixing can  also happen by accident.

(FM modulation is one of examples of  frequency change)

Hi Wesley,

My question was not addressed to you, it was addressed to Erfandl who started this thread.
