Pronunciation /vōlt/ /voʊlt/

noun

  • The SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.

    • ‘They created electricity running at 10 volts with a milliamp current, enough to power a small lightbulb.’
    • ‘Lightening is a discharge of static electricity that ‘contains’ millions of volts of potential difference and many thousands of amps of electrical current.’
    • ‘As discussed previously, voltage is measured in volts, and current is measured in amps.’
    • ‘Because powerlines are typically 400,000 volts, and Earth is at an electrical potential of zero volts, pylons create electric fields between the cables they carry and the ground.’
    • ‘A 19 year old man suffered serious burns after climbing 30 feet up an electricity pylon carrying 30,000 volts.’
    • ‘These cables carry in the order of 13,000 volts of electricity.’
    • ‘This a distribution power line, and the utility crews have told me that these sorts of lines normally carry 7,600 volts of electricity.’
    • ‘A news report said the line carried 13,000 volts of electricity.’
    • ‘At the rear of the engine is a pair of rectangular metal grids that are charged with 6,000 volts of electric potential.’
    • ‘Once it's charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor).’
    • ‘If only amperage is listed, the formula to determine watts is: amps times volts equal watts.’
    • ‘Noise signal out is generally given in amps per Hz or volts per Hz.’
    • ‘It is defined as the energy lost or gained by an electron as it passes through a potential difference of one volt.’
    • ‘Invented in 1985, modern-day magnetic stimulators charge up to a whopping 3,000 volts and produce peak currents of up to 8,000 amps - powers similar to those of a small nuclear reactor.’
    • ‘The instrument is able to measure isotopes at the individual atom level and does so by generating millions of volts of electricity.’
    • ‘The person doing the conversion decides what voltage the system will run at - typically anything between 96 volts and 192 volts.’
    • ‘Next door to the proposed site is a massive electrical substation with overhead power cables carrying 33,000 volts.’
    • ‘The characteristic voltage is about 2 volts per cell, so by combining six cells you get a 12-volt battery.’
    • ‘Like 220 volts of current being forced through a 110-volt kitchen appliance, the system is becoming overloaded, and the smoke is rising.’
    • ‘The car's inverter voltage was increased from 500 volts to 550 volts and the petrol engine's electronic management system was altered to allow it to rev higher.’
