Volt is unit of measure:
Volt – unit of electrical potential, potential difference, voltage and electromotive force in the International system of units (SI), named after the Italian physicist and physiologist Alessandro Volta.
Volt as a unit of measurement is the Russian designation In the international designation – V.
There are several definitions of a volt.
The potential difference between two points is 1 volt (C) if the moving charge magnitude of 1 Coulomb (C) from one point to another above it is necessary to perform work quantity 1 Joule (j).
1 volt (V) an electrical tension that caused in the electric circuit a constant current of 1 ampere (A) at a power of 1 watt (W). Or 1 volt is equal to the electric voltage at the ends of the conductor necessary for the allocation in this heat with a power of one watt (W) when power flows through the conductor DC at one ampere (A).
1 volt (V) is equal to the potential difference across the resistor in 1 Ohm (Ω) when the flow through it of current in 1 ampere (A).
A = (m2 · kg) / (S3 · A) = j / KL = A / Ω = W / a = A · Ohms.
1 = (1-m2 · 1 kg) / (C3 1 · 1 A) = 1 j / 1 C = 1 A / 1 Ohm = 1 watt / 1 A = 1 A · 1 Ohm.
In the International system of units volts, put the decision of the XI General conference on weights and measures in 1960, simultaneously with the adoption of the SI as a whole. In accordance with the rules SI, and relating the derived units are named for scientists, the name of the unit “volt” is spelled with a lowercase letter and its name — with a capital (In). Such writing of the designation is stored in the symbols for derived units formed by using the volt.
The application volt:
Volts measure electric potential, potential difference, voltage and electromotive force.
Representation of the volt to other units – of the formula:
Through the basic and derived SI units volts is expressed as follows:
A = (m2 · kg) / (S3 · A)
In = J / KL
In = A / Ω
V = W / A
V = A · Ohms
where A is amperes, In volts, KL – pendant, j – Joule, m = meter, s – second W – watt, kg – kilo, of om – Om.
Multiple and fractional units of volts:
Multiple and sub-multiple units are formed using standard prefixes of the SI.
