(unit of measurement of electromotive force, or pressure, in an electrical circuit, or 'push', named for Alessandro Volta (1745-1827) renowned for his pioneering work in electricity)
The thermal radiation emitted by the absorber is used as the energy source for a photovoltaic cell that is designed to maximize conversion efficiency at the wavelength of the thermal radiation.
2. The minimal voltage at which all the pulses produced by an ionizing even are of the same size regardless of the magnitude of the event.
2. A locked room where money or valuable things are kept: "I had never been in the bank vault before."
2. A quick jump or movement during fencing to avoid a thrust: "The fencing master taught the students how to use the volt so their opponents couldn't score."
When the man was exploring the ancient vault under the market square, he carried a nine volt battery for his portable light so he could see if he needed to vault over the broken stones.
2. A unit for the integral of apparent power over time, equal to the product of one volt-ampere and one hour.
2. An electric measurement unit, equal to the product of one volt and one ampere, equivalent to one watt for direct current systems and a unit of apparent power for alternating current systems.
3. A unit of electric measurement equal to the product of a volt and an ampere that for direct current constitutes a measure of power equivalent to a watt.
The common voltage of an AC power line is 120 volts of alternating current (alternating directions) while common voltages within a computer are from 3 to 12 volts of direct current (one direction only).2. The unit of potential difference or electromotive force in the meter-kilogram-second system, equal to the potential difference between two points for which one coulomb of electricity will do one joule of work in going from one point to the other.
Electric potential is the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Typically, the reference point is the earth, although any point beyond the influence of the electric field charge can be used.3. A standard unit of potential difference or electromotive force equivalent to the potential difference between two points requiring one joule of work to move one coulomb of electricity from the point of lower potential to the point of higher potential. 4. A unit of electrical force equal to that amount of electromotive force that will cause a steady current of one ampere to flow through a resistance of one ohm.
5. The standard unit used to measure how strongly an electrical current is sent around an electrical system.
2. The potential difference between two electrodes, as measured in volts.
3. The rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts.
Voltage is often compared to water pressure or are often given relative to "earth" or "ground" which is taken to be at zero volts. A circuit's earth may or may not be electrically connected to the actual earth.4. A term sometimes used interchangeably with electrical potential.
The electrical potential difference between two points in a circuit is the cause of the flow of a current.
Voltage is measured in volts, millivolts, microvolts, and kilovolts and the terms electromotive force, potential, potential difference, and voltage drop are all often called voltage.
The voltage gain of the amplifier is the amplitude ratio of the output voltage to the input voltage.2. An amplifier designed primarily to build up the voltage of a signal or to increase a signal's voltage, without supplying appreciable power.
It is expressed in decibels by multiplying the common logarithm of the ratio by 20.
