@Circuitfantasist I tried your executable Flash movie and found it impressive. I would give 9/10 marks on presentation style. Of course, as I said, Flash is now replaced by HTML 5. I am not suggesting you to switch to HTML5. I would think YouTube might be a good alternative. As I told you some time ago, I once tried the YouTube based MIT OCW free online course to learn EE101 and python and found it very good.
Anyway, I played you Flash movie on my Chinese Win10 PC and so far so good. I would explore further later.

I watched the current loop and potential bard and found two things you might consider to improve: (1) Current magnitude is represented by thickness of the loop path. This is not very obvious. Perhaps you can make the thickness change increments bigger, or at the same time use darker colours to represent bigger current. (2) This is more misleading: the potential bar is below the resistor, NOT across the resistor, ...

Hi Fong! First watch this video for a little fun:)
Yes, the magnitudes of quantities can be coded in various manners if only there is a good attitude towards this visualization technique. But when someone writes to you that these "lines" prevent you from seeing the diagram, what do you have to do?
Voltage bars are interdependent and the sum of the voltage drops across the elements in series is equal to the supply voltage (a "geometric KVL"). They do not always match the resistors, especially if the voltage drops are with a negative polarity. But this corresponds to the real situation. I had an idea to use them as an output of a simulating program... and even suggested it...

Ah, our chat has become TLDR and diverted too far from the original main topic of negative resistance and tunnel diode. Since you have already created a blog post for the I-Loop/V-bar graph discussion, I suggest that we CLOSE THIS CHAT ROOM, and continue our discussion in your blog.

What will happen with this chat after the closing? Will it stay here or it will be deleted?

Ah, don't worry. My experience tell me that you can still visit any closed chat room. Any chat room without any activity will be frozen. Let me verify and confirm you later.
Just now I visited one of my old TLDR chats a couple of months ago. It is still there. You might like to visit it to see if you can read it.
