Hello again guys. I've been reviewing stuff from electromagnetism and I just recently read about voltage. I know it is a difference of potential, electric potential more precisely. Electric potential is just a property of electric fields and it is measured in Joules per Coulomb. 1 Joule per Coulomb is the energy spent in moving a 1 Coulomb charge across a potential difference of 1 Volt. However, when it comes to more or less voltage I can´t distinguish any difference. I can just say 12 V is just the same amount of charge being moved across 12 V and 12 J being spent by the electric field because of that. I know current is proportional to voltage but in many cases there are tiny currents caused by huge voltages so it is not a good reference to me. What does more voltage actually mean? By the way, please don't relly on the hidraulic analogy, it never explained anything to me.
Thank you :)
Thank you :)
