-‘1 volt’ is defined as the ‘electric potential’ between 2 points of a ‘conducting wire’ when an ‘electric current’ of ‘1 ampere’ dissipates ‘1 watt’ of ‘power’ between those ‘points’-
(WATTS / AMPERES)
.
.
-IT CAN BE DEFINED AS [JOULE] / [COULOMB]–

*the ‘derived unit’ for…*
“electric potential”
‘electric potential difference’
(aka ‘voltage’)
‘electro-motive force’
.
[VOLT] = [[WATTS] / [AMPERE]]
(“power” / “electric current”)
.
.
(the ‘volt’ is named in honor of the italian physicist ‘alessandro volta’ (‘1745’ – ‘1827’), who invented the ‘voltaic pile’)
(possibly the first ‘chemical battery’)

‘VIN’
(‘voltage input’)
(formally denoted ∆V or ∆U…)
(…but more often simply as V or U)
(for instance in the context of Ohm’s or Kirchhoff’s laws)
.
(it is the difference in ‘electric potential energy’ between 2 points per ‘unit electric charge’)
.
(the ‘voltage’ between 2 points is equal to the ‘work done’ per ‘unit of charge’ against a ‘static electric field’ to move the ‘test charge’ between 2 points and is measured in units of volts (a ‘joule’ per ‘coulomb’))
.
[‘voltage’ can be caused by…]
‘static electric fields’
*’electric current’ through a ‘magnetic field’*
*’time-varying magnetic fields’*
(…or some combination of these 3)
.
(a ‘volt-meter’ can be used to measure the ‘voltage’ (or ‘potential difference’) between 2 points in a system…)
.
(…often a common reference potential (such as the ‘ground’ of the ‘system’) is used as 1 of the points)
.
(a ‘voltage’ may represent either a source of ‘energy’ (‘electro-motive force’), or [lost / used / stored] energy (‘potential drop’))
