I guess language may be the culprit, and the problem itself is probably somewhat philosophical. To answer your question, I am trying to wrap my head around what "quantity" is. Normally, I would figure out the meaning of a concept quite quickly, but in this particular case, I couldn't find a...

Thanks a lot for your answer. You state that you would call properties that are broken down into smaller pieces, quantities. In other words, you describe quantity as a product of property analysis. But where do properties end and quantities begin? To use your example, a car engine is a single...

The title pretty much says it all, but let me elaborate on the source of confusion. VIM defines quantity as: Other definitions I found are extremely circular. They typically go like this, "a physical quantity is a property that can be quantified". In other words, they explain quantity with...

I am sorry if I have offended you in any way. When I was referring to "things I am reading don't add up to what's happening in the real world", I meant articles I read online which tend to be inaccurate. I wasn't addressing the posts in this thread. I am only trying to understand, not to be a...

Sadly, this statement confuses me even more. It sure won't make a difference to the way batteries work if I understand what causes voltage to increase, but I become restless when what I read doesn't add up to what happens in the real world. I don't like giving up so easily. :) I think I have...

Therefore, voltage would be the same as "current" if there is no resistance in the circuit, right? If we remove resistance from the equation what would voltage (=current) represent? The formula Q/t doesn't explain a lot. Would you please elaborate on what current actually means in terms of...

This is exactly like the image I was looking at when I read about the Galvanic cell. I can imagine adding two more electrodes in the system and connecting the four electrodes to the voltmeter. This should increase voltage, no? OK. So therefore, the cathodes and anodes in each battery do...

Thanks for all of you for your insighful replies! Still though, are the electrons flowing from the "+" to the "-" as by convention, or do they travel vice-versa? Also, why is there a need for a bridge between the two chemical to complete the circuit, when chemical 1 has extra electrons and...

Thanks again for your replies, but I obviously haven't understood battery design very well and this confuses me a lot. Can you please describe in really simple terms how a battery operates or at least refer me to a source that will help me understand it better?

Thanks so much for your reply, but I still don't understand why voltages get added when it comes to the wire circuit. Suppose two 1.5V batteries are connected in series to power a single circuit. The batteries have 4 cells (1 positive and 1 negative per each) and 2 separators in total. The...

Hey! I am looking into how batteries work but I can't understand why -- from a chemical perspective -- voltage increases when they are connected in series. Let's say we have two identical batteries: battery 1 at the bottom and battery 2 on top, connected in series. The negative bottom end...
