able to set batteries up in series but not parallel

don't diodes block current from going into the tip of triangle flat side? When turning off conventional current it seems the diode works in reverse in relation to the flow

Yes cause turning of conventional current actually reverses the way how current is displayed. So conventional current theoratical shows the flow of protons going from + to -. Physical current then shows the drift of electrons from - to +. In reallity protons cant move around so physical current is the way how it „really“ is. Still conventional current is standart in electronics.

thank you Mr V. it seems that the components have their own set of parameters for conventional vs non conventional. its like the components dont react to the change despite the program having the option of reversing the current unless i need to remove the components and restart with the "real" way?

its confusing to me whyen non conventional works with diodes going in reverse. figure nothing should be going through at all or very little current ....not enough to light up the led.

Hm okay. First i need to correct myself, its not "physical", thats out of my bad translation. It was ment to refer to physics and not to sport haha. Anyway i will just call it electron flow from now. So you are maybe overthinking this a little bit. It doesnt revers any of the working principles, just the way you look at it. What happens in your conductor/ compnents stays the same. As i mentioned, protons cant move so in physics electrical current is defined as the move of electrons. But on the other hand, if you apply a voltage to pice of wire, a electron drifts from a neutral place (in the wire) to a positiv charge and the first place it was in, gets charged positiv and the second place becomes neutral. So basically you could say that the positiv charge has lmoved. And if you look at the pn-regions of the diode in respect to the schematic symbol, it will make sense both with conventional current and the actual drift of electrons.

Thank you Mr. V that clears up a lot. yeah over thinking is an issue of mine. so the reversal of the current is just for display only but doesn't actually change how current is actually traveling in real time. i am for sure going to fry something when transferring these schematics into real time applications. thank you for your lesson.

ive added an second circuit but the simulator says its shorted which does mot make sense to me. in a real life set up this works like for battery banks in series i think. (positive to positive and negative to negative keeps voltage the same). the simulator does not like this set up. i can hook batteries up in parallel in the simulation and it adds the voltage like is supposed to. not sure if i did something wrong or the sim isnt programmed to use batteries in such away.

Yes i know this issue. So basically the power supplies in EC are ideal so they would deliver infinte current when shorted but i dont know how you could simulate that...So there is no practical reason to add them in parallel cause jusr one of them will do the same thing. But if you need it to make a schematic complete you can just add a resistor with the lowest possible value between them. Also just a little tip, you mixed up parallel and series a little bit haha. They are parallel right now and to add their voltages you will put them in series.

sadly no change. i even tried reversing the two batteries just in case. one way would have neg 2 between them and the other way gave me a pos 2. resistor didnt do anything between them, since it seems with that set up it wont let current flow. through the batteries and act like a battery bank of sorts unless maybe there is some other way to set up two batteries in the same fashion and have it work as one big battery with the same voltage. maybe im missing something

it just be because no matter which way the batteries are in parallel in the circuit with the positive or negative terminals are facing each other so it considers them canceled out? the only reason im doing this is im setting up a couple of battery banks that im able to switch between and i want to be able to visualize it and make sure i know what im doing. like a plan of sorts.

I get those parallels mixed up cause in parallel parking [+_--] [+_--] but I should remember it's not necessarily the poison of battery that makes it series or parallel it's in fact the way the terminals are connected but I keep going going back to parallel and how cars are front to back to front connect to the back . I confused the hell out of my explanation but yeah

Some batteries may explode when placed in parallel especially when is a rechargable bank. To prevent this place a diode at positive terminal of every battery. It works on simulation too.
