Как преобразовать электрическое напряжение в вольты (В) to energy в electron-volts (эВ).
You can calculate electron-volts from volts and elementary charge или coulombs, but you can't convert volts to electron-volts sвce volt and electron-volt units represent different quantities.
Энергия E в electron-volts (эВ) is equal to the voltage V в вольты (В), times the электрический заряд Q в elementary charge или proton/electron charge (e):
E(эВ) = V(В) × Q(e)
The elementary charge is the электрический заряд of 1 electron with the e symbol.
Таким образом
электрон-вольт = вольт × элементарный заряд
или
эВ = В × e
What is the energy в electron-volts that is consumed in an electrical circuit with voltage supply of 20 volts and charge flow of 40 electron charges
E = 20В × 40e = 800эВ
Энергия E в electron-volts (эВ) is equal to the voltage V in вольты (В), times the electrical charge Q in coulombs (Кл) divided by 1.602176565×10-19:
E(эВ) = V(В) × Q(Кл) / 1.602176565×10-19
Таким образом
электрон-вольт = вольт × кулон / 1.602176565×10-19
или
эВ = В × Кл / 1.602176565×10-19
What is the energy в electron-volts that is consumed in an electrical circuit with voltage supply of 20 volts and charge flow of 2 coulombs
E = 20В × 2Кл / 1.602176565×10-19 = 2.4966×1020эВ
