about-face, act of turning to face the opposite direction from the original position (Military); complete change in position or attitude; sudden reversal in opinion or policy
If you say that someone's behaviour is a volte-face, you mean that they have changed their opinion or decision completely, so that it is the opposite of what it was before. The day's events were a remarkable volte-face. = about-face. a change to a completely opposite opinion or plan of action = U-turn
In the International System of Units, the derived unit of electrical potential and electromotive force (voltage); the potential difference across a conductor when a current of one ampere uses one watt of power. Symbol: V
In the International System of Units, the derived unit of electrical potential and electromotive force (voltage); the potential difference across a conductor when a current of one ampere uses one watt of power. Symbol
The unit of measure for voltage Voltage is the electrical pressure which forces the current to flow in a conductor such as a wire Volt-Ampere (VA) Voltage (V) multiplied by the current (ampere); apparent power For instance, a device rated at 10 amps and 120 V has a VA rating of 1200 or 1 2 kVA
A volt is a unit used to measure the force of an electric current. The International System unit of electric potential and electromotive force, equal to the difference of electric potential between two points on a conducting wire carrying a constant current of one ampere when the power dissipated between the points is one watt. See table at measurement. a unit for measuring the force of an electric current (Alessandro Volta)
== The volt is the unit of electrical measurement named after the Italian physicist, Conte Alessandro Volta 1745-1827 Volta was Professor of Physic at the University of Pavia from 1779, and invented what is new known the voltaic pile, in which a charge of electricity is created by induction The volt is the pressure that pushes the current down the line Think of it as analogous to pounds per square inch of pressure in hydraulics Normal electrical pressures in American homes are 120 for lighting circuits, and 240 for such appliance, as stoves, dryers, and water heaters In Europe, 240 is standard The volt is the unit of electromotive force, or emf
The unit of measurement of electromotive force necessary to produce one ampere of current in a circuit having a total resistance of one ohm The volt is named for Alessandro Volta, an 18th century Italian physicist
a unit of potential equal to the potential difference between two points on a conductor carrying a current of 1 ampere when the power dissipated between the two points is 1 watt; equivalent to the potential difference across a resistance of 1 ohm when 1 ampere of current flows through it
The standard unit of electromotive force or electrical pressure One volt (1 V) is the amount of pressure that will cause one ampere (1 A) of current to flow through one ohm of resistance
The unit of electro-motive force; defined by the International Electrical Congress in 1893 and by United States Statute as, that electro-motive force which steadily applied to a conductor whose resistance is one ohm will produce a current of one ampère
A unit of electrical pressure It measures the force or push of electricity Volts represent pressure, correspondent to the pressure of water in a pipe A volt is the unit of electromotive force or electric pressure analogous to water pressure in pounds per square inch It is the electromotive force which, if steadily applied to a circuit having a resistance of one ohm, will produce a current one ampere
Unit of potential difference or electromotive force One volt is the potential difference needed to produce one ampere of current through a resistance of one ohm Voltage is the driving force throughout a sound system from the microphone input to the speaker terminals
The meter-kilogram-second (MKS) unit of electromotive force, or potential difference; the potential difference between two points in an electric field such that one JOULE of work moves a charge of one COULOMB between these points The electrical force that, if steadily applied to a circuit with a resistance of one OHM, will produce a current of one ampere
[ "volt-'fäs, "vol-t&- ] (noun.) 1819. French, from Italian voltafaccia, from voltare to turn + faccia face, from Vulgar Latin facia; more at VOLT, FACE.
