One volt is defined as the electric potential between two points of a conducting wire when an ... Ohm's law), webers per second (magnetic flux per time), watts per ...
The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop. A change in flux of one weber per second will induce an electromotive force of one volt (produce an electric potential difference of one volt across two open-circuited terminals).
Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. [1] [2] In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point.
where V(t) is the resulting voltage across the circuit, I(t) is the current through the circuit, and L is the inductance of the circuit. The henry is a derived unit based on four of the seven base units of the International System of Units: kilogram (kg), metre (m), second (s), and ampere (A). Expressed in combinations of SI units, the henry is ...
This law, also called Kirchhoff's second law, or Kirchhoff's loop rule, states the following: The directed sum of the potential differences (voltages) around any closed loop is zero. Similarly to Kirchhoff's current law, the voltage law can be stated as: = = Here, n is the total number of voltages measured
Volt-ohm meter (VOM), instrument that combines several electrical measurement functions volt-second (V⋅s), more commonly the weber (Wb), a unit of magnetic flux Volts Center Tapped (VCT), a unit of voltage output of a center tapped transformer
In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit).
High Voltage Alternating Current; depending on context, this could be hundreds or hundreds of thousands of volts. HVDC converter station An element of a high-voltage direct current power transmission system; each end of the transmission line has a converter station connected to the local AC grid.
