By definition, 1 V is a potential energy difference of one joule PER COULOMB of charge between two points.Hi. By definition, "...Volt is a potential energy difference between two points....."
So what is 1.5V, 9V or 12V really means?
Force is measured in newtons, not joules.voltage is the measurement of electric force between two points of the same circuit, the bigger the force the bigger the voltage is displayed.
It's an inherited travesty due to the sloppiness of previous generations made at a time both when things weren't nearly as well understood and also when rigor and consistency weren't as valued. Using the term "force" in this context is deprecated and causes all kinds of confusion because you tell people that something is a "force" when it isn't and, not surprisingly, they think that it is a force, when it isn't. This is made all the worse since there very much IS an electric force, namely the force exerted on one charged particle by all other charged particles.
The term "force" is perfectly applicable in the electromagnetic realm, but you are correct that it is not appropriate for describing voltage because voltage does not describe a force. The very notion of voltage and electric potential come directly from Coulomb's Law describing the force -- as in F=ma force -- between two charged particles."Force" is a mechanical term and I don't think it's appropriate for describing voltage. "Potential" seems to be the preferred term.
I have to disagree with you there.Voltage is always a potential difference.
The electric field is measured in the same units as all electric fields, namely N/C. You can also express that in V/m. You cannot express the electric field in volts, since volts is not a measure of electric field.I have to disagree with you there.
Consider a thought experiment in a universe with only one single electric charge.
There is an electric field emanating from that charge in all directions.
What units do you measure that field in?
