What will happen if we have taken galvanic element having voltage 0.1v(may be potato  :D ) and loaded by tunnel diode? In that place  its current-voltage characteristic, which has a negative differential resistance .

Thank you for taking the time to respond to my previous message. While I appreciate your expertise in the field, I must admit that I am confused by some of the points you have made.

In particular, I have been trying to understand your assertion that a loop configuration using earth batteries with no resistor in line does not create a short circuit. As I understand it, connecting the positive and negative terminals of a battery together without any resistance does create a short circuit, which can cause the battery to discharge quickly and even become damaged.

I have tried to explain this concept in more detail in my previous messages, but it seems that you are still convinced otherwise. If you could please provide more information or evidence to support your claim, I would be happy to consider it.

Furthermore, I must express my disappointment at the tone of your message. I am here to learn and expand my knowledge, and I believe that we can have a productive and respectful discussion despite any differences in understanding. It is not constructive to dismiss someone as a lost cause or an amateur.

connecting the positive and negative terminals of a battery together without any resistance does create a short circuit,
The answer:
Quote
Some of the energy given by the potato cell is used up in the cell itself through having to push the electrons through the system; this is called internal resistance.
add on the top of it  resistance of two windings the modulation transformer and  the L1/L2 transformer.
To have effective  signal out  you need to deliver  from the microphone into modulating  transformer  primary winding 
48V for standard condenser microphone and 
~12V for standard dynamic microphone.( varies)
while your  power  from potato cell is  around :
The potato doesn’t actually produce any electricity. Rather, it’s the metals inserted into the potato slowly dissolving and releasing electrons.
A single potato battery only produces about half a volt.at 0.01A in average.
this value becomes insignificant at presence of AC there  and it dissipates along windings.
how-much-electricity-can-a-potato-generate.
The circuit in that video will see the DC offset level at the  noise level.
 our potato will become part of the AC circuit between two transformers and its  desired DC function  is no longer  important.
 That is why   I have ask you in previous comment to measure resistance of potato.
For example:
Quote
A transformer that steps the impedance up by a factor of somewhere between 10 and 100 and the voltage by a
factor of somewhere between say 3 and 10 (Impedance transformation is always the square of the voltage transformation
in a transformer) is almost mandatory with these and often built in.
In the simple language  because you didn't specify power delivered by modulating  signal I said that  circuit will work.
Think about 1000 dollar transfer  in AC while DC offset is  2 cents.

How many potatoes does it take to light an LED?
Quote
If you have an LED, 2 potatoes should be enough to light it. You can also use a voltmeter/multimeter
to measure the voltage passing through.

Thank you for sharing the additional information. I appreciate your efforts to clarify the issue of short circuits and their relation to earth batteries. However, I feel that the discussion shifted away from the original topic and onto unrelated matters, such as microphones, general voltage rules, ohm's law basics etc...

I would like to respectfully suggest that we return to the original focus on the loop configuration using earth batteries, as this is the topic that I am most interested in. While I understand that there may be other related concepts and ideas worth exploring, I believe that we can have a more productive conversation if we stay on topic.

I am happy to engage in further discussion and share my own insights and knowledge, but I would appreciate it if we could stay focused on the specific issue at hand. Thank you again for your time and input.

My fried It didn't shift at all.
You by yourself  placed on your schematic wording "input Audio" !!!
You need  microphone to create AC that can be transformed by your transformer.
And than you need impedance match between transformer and your microphone as a source of
AC. Transformer can't  transform DC.!! -and  to  have  any AC left so the second transformer can transform something
whatever is left there - so you need impedance matching between the two  transformers as well.
And than you need impedance matching  between  output of second transformer and your antenna.
I'm sorry but I thought  that this is understood. 
It is also worth to mention that 1 loop of copper wire at 1m diameter  and 1cm thick is short circuit for  DC  but  it can have
significant  impedance to AC. frequency sensitive)
The standard for antenna and  transmission line is 50 OHm

Sir, simply screaming louder and louder calling an apple "banana" is not going to change the basic fundamental fact. I addressed your points earlier in the post. My points are indeed valid. I'm sorry about that. Instead of rambling, Please move on or provide relevant information to my post.

Thank you  8)

Sorry it looks like we  have problem in communication .
I  kindly suggest  to  ask others for  help
That's enough  of potato battery  for now.
I'm mostly in particle  physics but antennas, transmission lines , modulation , Tx/Rx
propagation, energy transfer  was for the past several years major task in one of my labs.
I wish you the best.

As I mentioned earlier I addressed your issues in past replies, pardon the expression but I have to say.  I'm not going to repeat myself in a "loop" here and play part of your silly little game  :o

I know i'm correct. Science is on my side here. And I will use your expression by stating people here know my methods and devices are not a bunch of "crab" as you would describe it.

You seem specifically fascinated with microphones and audio amps. From what I can tell in some of your repetitive replies. If you want. I can provide you some great Wiki links, That explain the inner workings of such devices. Perhaps once you learn about something interesting in such systems, Perhaps You can start your own post in some forum and discuss the workings of such systems all day and night with your fellow peers.

It's great that your into particle physics, If I were you, I'd stick to particle physics, Because I really think basic electronics is really just not made for you. What I address here is grade 9 level kind of stuff in relation to "DC short" However you want to warp that... Have at it buddy!

Kind regards!

Dear joellagace.
How if you right and good and sparkling and enlightening... you have great potential, and nothing you said  was crab or crap.
How if I was wrong,  And now all of the members know that .
How much did you gain by that?
