I’ve heard the definitions of it being “energy transferred per charge”, “potential difference”, and “the difference between the electrons in the positive and negative terminals of a battery” but I still don’t really understand some of these definitions, and can’t really wrap my head around what exactly is it.
I also don’t really get how it is the thing that can “power up” a circuit (I might have misunderstood this part” and how the definitions above can be the same thing
In: Physics
This is a common sticking point for lots of people, so I have to ask where do these definitions lose you? A flow of electricity is *moving charges*, and voltage can be understood as the quantity of energy required to move a *unit* charge (any small reference charge – the SI unit being the *coloumb*) from one point to the other.
