joule Význam & definícia

Príklady joule

• This electric field reduces the penetration of the hot electrons, but also implies an enhanced joule heating of the bulk electrons.

• Three joule meters measure the incident, transmitted and reflected pulse energies, respectively.

• In the case of electrical (or joule) heating, heat transfer is dictated by the level of current applied.

• By combining these values, one can obtain for a few hundred microns spot the necessary laser energy of about several hundred joules.

• We defined the latter as the electron number in the plasma jet volume per one joule of the laser energy.

• The reflected and transmitted energies were directly measured using joule meters.

• It is measured in joules per kelvin.

• The joule is accepted by scientists as being the correct unit for energy.
