  2. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power converters include simple devices such as transformers, and more complex ones like resonant converters.

  3. Joule - Wikipedia

    en.wikipedia.org/wiki/Joule

    One square metre of the Earth receives about 1.4 kilojoules of solar radiation every second in full daylight. [20] A human in a sprint has approximately 3 kJ of kinetic energy, [21] while a cheetah in a 122 km/h (76 mph) sprint has approximately 20 kJ. [22] One watt-hour, of electricity or any other form of energy, is 3.6 kJ. megajoule

    1 kJ/mol, converted to energy per molecule [9] 2.1×10 −21 J Thermal energy in each degree of freedom of a molecule at 25 °C (kT/2) (0.01 eV) [10] 2.856×10 −21 J By Landauer's principle, the minimum amount of energy required at 25 °C to change one bit of information 3–7×10 −21 J

  5. Electronvolt - Wikipedia

    en.wikipedia.org/wiki/Electronvolt

    An electronvolt is the amount of energy gained or lost by a single electron when it moves through an electric potential difference of one volt.Hence, it has a value of one volt, which is 1 J/C, multiplied by the elementary charge e = 1.602 176 634 × 10 −19 C. [2]

  6. Charge amplifier - Wikipedia

    en.wikipedia.org/wiki/Charge_amplifier

    The charge signals at the input of a charge amplifier can be as low as some fC (FemtoCoulomb = 10 −15 C). A parasitic effect of common coaxial sensor cables is a charge shift when the cable is bent. Even slight cable motion may produce considerable charge signals which cannot be distinguished from the sensor signal.

  7. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A voltage converter is an electric power converter which changes the voltage of an electrical power source. It may be combined with other components to create a power supply . AC and DC

  8. TNT equivalent - Wikipedia

    en.wikipedia.org/wiki/TNT_equivalent

    The complete conversion of 1 kg of matter into pure energy would yield the theoretical maximum (E = mc 2) of 89.8 petajoules, which is equivalent to 21.5 megatons of TNT. No such method of total conversion as combining 500 grams of matter with 500 grams of antimatter has yet been achieved.

  9. Marx generator - Wikipedia

    en.wikipedia.org/wiki/Marx_generator

    Marx generator diagrams; Although the left capacitor has the greatest charge rate, the generator is typically allowed to charge for a long period of time, and all capacitors eventually reach the same charge voltage. The circuit generates a high-voltage pulse by charging a number of capacitors in parallel, then suddenly connecting them in series ...
