And regarding 'learning style' I feel the same way as Mr. WJB: "When I went into engineering school, I found it extremely odd that there were still no good explanations of bipolar transistors. Sure, there were detailed mathematical treatments. Just multiply the Base current by "hfe" to obtain...

Thank you for trying to help me. The reason I'm so opsessed with this expression 'against voltage pressure/force' is that it's used by so many professionals and people who I considder true experts. That's why I was/am thinking that the most reasonable explanation is that they mean something by...

I need to be absolutely sure that I don't misinterpret the English language with regards to the word "against" in this specific context.

"Why would the charges need to be pushed agaisnt the very own field which made their flow possible in the first place?" This is what I'm asking! "VOLTS x COULOMBS = JOULES It takes energy to push some charge against the voltage pressure" So, how do read this sentence (I'm not talking about...

but the charge moves BECAUSE of the voltage force. When the sentence say the opposite - how can it be correct?

Jartsa: thanks. That was for me a concise explanation. The sentence imply to you that the charges move - in spite of - the voltage force, but this is wrong isn't it? In reality they move BECAUSE of the voltage force right? So the sentence is wrong?

This thing IS a question of wording. We 'agree' about these basic voltage things. My question was regarding the specific sentence (which I'm translating), if it says (THE SENTENCE) that the charges move because OR in spite of the voltage pressure/force?

Another question for you: Again, regarding this sentence: VOLTS x COULOMBS = JOULES It takes energy to push some charge against the voltage pressure Does this sentence imply to you that the charges move because of the voltage force or in spite of the voltage force?

sophiecentaur: I'm not asking for at metaphor, but a description. jartsa: yes, and how would you then interpret this: VOLTS x COULOMBS = JOULES It takes energy to push some charge against the voltage pressure here it doesn't say 'against resisting force' but 'against voltage pressure'...

That's abstract. I feel certain that one should be able to describe what's happening. It's not magic.

Maybe. I simply cannot understand why one would use this word 'against'. The em-energy flows almost instantly down through/along both wires to the load, and energy is consumed. This energy is needed to move the electrons (through the conductor and it's resistivity). The voltage makes the carge...

hm, I'm not sure if I have succeeded in explaining my qestion correctly. Thank you for your willingness to help.

Does 'against' mean the same thing as 'towards' in this case?

I see. Thank you. "Voltage is equal to the work done per unit charge against a static electric field to move the charge between two points." Also at wikipedia it says "against a static electric field". (Thanks for already trying to explain this to me). I just don't get this 'against'. How...

You're right, the field is the primary thing. I was obviously wrong saying you need both ohms and current (so to speak). But you do need resistance right? To have an e-field? If there were no electrical resistance between the two poles of the e-field it would just neutralize itself, yes?
