 bias voltage   ولتاژ ِ ورک   voltâž-e varakFr.: voltage de biais   A voltage applied or developed between two electrodes as a bias.→ bias; → voltage. cutoff voltage   ولتاژ ِ بره   voltâž-e boréFr.: tension de coupure   The electrode voltage which reduces the value of a dependent variable, e.g. anode current, to a specified low value.→ cutoff; → voltage. electron volt (eV)   الکترون-ولت   elektron-volt (#)Fr.: électron-volt   → electron; → volt. electron-volt (eV)   الکترون-ولت   elektron-volt (#)Fr.: électron-volt   The energy acquired by an electron when accelerated through a → potential difference of 1 volt (1 eV = 1.602 × 10-12 → ergs = 11605 → kelvins).→ electron; → volt. noise voltage   ولتاژ ِ نوفه   voltâž-e nuféFr.: voltage de bruit   Fluctuations of electric potential in a physical system due to spontaneous disturbances in the system.→ noise; → voltage. overvoltage   بیش‌ولتاژ   biš-voltâžFr.: surtension   Voltage which exceeds the normal value between a conductor and earth.→ over-; → voltage. photovoltaic detector   آشکارگر ِ شید-ولتایی   âškârgar-e šidvoltâyiFr.: détecteur photovoltaÃ¯que   A detector usually constituted by a p-n junction. Upon irradiation, the electron-hole pairs which are created, are immediately separated by the strong electric field across the junction, and a current is generated, which is proportional to the number of incident photons per second.→ photo- + → voltaic; → detector. volt   ولت   volt (#)Fr.: volt   The SI unit of potential difference, defined as the difference of potentials across the ends of a conductor in which a power 1 watt is liberated when a current of 1 ampere flows through it.In honor of the Italian scientist Alessandro Volta (1745-1827), known for his pioneering work in electricity and the invention of the first battery. voltage   ولتاژ   voltâž (#)Fr.: voltage, tension   The electric potential difference expressed in volts.From → volt. voltaic   ولتایی   voltâyi (#)Fr.: voltaïque   Of, relating to electricity or electric currents, especially when produced by chemical action, as in a cell. → photovoltaic detector.Alessandro Volta (1745-1827), Italian physicist, known for his pioneering work in electricity.
