English-French-Persian

A voltage applied or developed between two electrodes as a bias.

→ bias; → voltage.

The electrode voltage which reduces the value of a dependent variable, e.g. anode current, to a specified low value.

→ cutoff; → voltage.

→ electron-volt.

→ electron; → 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.

Fluctuations of electric potential in a physical system due to spontaneous disturbances in the system.

→ noise; → voltage.

Voltage which exceeds the normal value between a conductor and earth.

→ over-; → voltage.

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.

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.

The electric potential difference expressed in volts.

From → volt.

Of, relating to electricity or electric currents, especially when produced by chemical action, as in a cell. → photovoltaic detector.
