absolute volt (s) (noun)
, absolute volts (pl)
The potential difference necessary to produce a current of one ampere through an electric circuit with a resistance of one ohm (unit of electrical resistance): Because the production of absolute current and voltage must equal mechanical power, experiments that realize the absolute volt involve mechanical effects and are inherently difficult; usually, requiring many years to complete.
abvolt per centimeter
The centimeter-gram-second electromagnetic unit of electric field strength.
1. The centimeter-gram-second electromagnetic unit of electromotive force.
One abvolt is the difference of potential between any two points when one erg of work is required to move one abcoulomb of electricity between them; equal to 10-8 volts.
2. The unit of electromotive force in the electromagnetic centimeter-gram-second system.
One abvolt equals 10-8 volts in the absolute meter-kilogram-second system.
A curved molding on the face of an arch.
demivolt (s) (noun)
, demivolts (pl)
A half vault (volt); one of the seven artificial motions of a horse, in which it raises its front legs in a particular manner.
For an alternating voltage, the root-mean square voltage.
electrode potential, electrode voltage
1. The potential developed by a metal or other electrode material immersed in an electrolytic solution; usually related to the standard potential of the hydrogen electrode, which is established at zero.
2. The instantaneous voltage of an electrode with respect to the cathode of an electron tube.
3. The voltage existing between an electrode and the solution or electrolyte in which it is immersed.
electron volt, electronvolt, eV
1. A unit of energy equal to the energy acquired by an electron falling through a potential difference of one volt.
2. A unit of energy defined as the kinetic energy acquired by an electron that is accelerated through a potential difference of one volt; equivalent to 1.6022 x 10-19
3. A unit of energy used in atomic and nuclear physics, equal to the energy gained by an electron.
4. A unit of electrical energy used in nuclear physics.
It is equal to the energy gained by an electron when it moves from one point to a point higher in potential by one volt and it is a unit of energy or work, not of voltage.
electronic alternating-current voltmeter, electronic alternating current voltmeter
1. A voltmeter consisting of a direct-current milliammeter calibrated in volts and connected to an amplifier-rectifier circuit.
2. A device that measures voltage in amplifier-rectifier circuits.
1. An instrument that measures voltage according to the degree of attraction or repulsion between charged bodies.
2. A voltmeter which works by measuring the force exerted between stationary electric charges which is usually graduated in volts or kilovolts.
3. A voltmeter in which the voltage to be measured is applied between fixed and movable metal vanes.
The resulting electrostatic force deflects or turns the movable vane against the tension of a spring.
1. A unit of voltage equal to 10-15 volts.
2. A unit of potential equal to one quadrillionth of a volt, or one thousandth of a nanosecond.
galvanic couple, voltaic couple
1. The connection of two dissimilar metals in an electrolyte that results in an electrical current flow through the circuit.
2. A pair of unlike substances; such as, metals, which generate a voltage when brought in contact with an electrolyte.
3. Two dissimilar conductors in contact or in the same electrolytic solution, resulting in a difference of potential between them.
gigaelectronvolt, gigaelectron volt, gigaelectron-volt; GeV
A unit of energy, used primarily in high-energy physics of one thousand million or one billion electron volts.
One billion volts.
The half-cycle of alternating current in which there is no current or no minimal current flow through the electrical component or equipment.
