Thanks to everybody. Thanks to Lost_Bro, for his comments.
For the moment, I'm interested in very basic "theoretical" stuffs.
I just made a new quick experiment:
= you can get voltage out of an air core coil wrapped with aluminium foil (as to build a kinda "capacitor")
even if this coil is just 'excited' by this fictitious displacement current.
You have to find the right ("resonant") freq.
Grounding/Eathing one particular end of the coil strongly increase the output voltage and change the "resonant" freq.
First results. No load. No "OU" claimed.The "capacitor" :
From 260 pF to 410 pF according to 2 different f' cheap meters.The coil:
Air core coil. From 19 to 22 Milli Henrie according to 2 different cheap bl' meters.
The Freq. Gen is given for: Max freq 3 MHZ. (Mine can goes a little bit further (3.15)).
Max output 10 volts
Actually, according to my scope:
At 3 MZH the Freq. Gen. output voltage (with not load) is only about 5 volts PK-to-PK.
At freqs less than about 500 KHZ this voltage is about 20 Volts PK-to-PK.
Sine wave as CCT input. CCT Output volts-wise only. With no load.Not
Feq. Gen. output (= CCT input)about 20 volts PK-to-PK.
CCT output about 2 volts PK-to-PK at about 150 Khz.
Feq. Gen. output (= CCT input) about 5 volts PK-to-PK
CCT output about 20 volts PK-to-PK
at about 3,07 Mhz.
--------------------Something seems to be going on, here. No.?
These are just first results. The numbers have to be confirmed. The circuit (CCT) have to be loaded.
Very very easy to reproduce. This experiment is for the slackers like me.
Take any off-the-shelf enameled copper wire spool.
It has to have his 2 ends available, of course.
Wrap it with some kitchen aluminium foil around it.
You have made a "capacitor".
Use a crocodile clip for connecting one "plate" of you cap.
Follow the picture and utilize your favorite Freq. Gen. and Oscilloscope.
