如何转换 电压 中的 伏特 (V) to energy 中的 electron-volts (eV).
You can calculate electron-volts from volts and elementary charge 或 coulombs, but you can't convert volts to electron-volts s中的ce volt and electron-volt units represent different quantities.
能量 E 中的 electron-volts (eV) is equal to the voltage V 中的 伏特 (V), times the 电荷 Q 中的 elementary charge 或 proton/electron charge (e):
E(eV) = V(V) × Q(e)
The elementary charge is the 电荷 of 1 electron with the e symbol.
所以
电子伏特 = 伏特 × 基本电荷
或
eV = V × e
What is the energy 中的 electron-volts that is consumed in an electrical circuit with voltage supply of 20 volts and charge flow of 40 electron charges
E = 20V × 40e = 800eV
能量 E 中的 electron-volts (eV) is equal to the voltage V in 伏特 (V), times the electrical charge Q in coulombs (C) divided by 1.602176565×10-19:
E(eV) = V(V) × Q(C) / 1.602176565×10-19
所以
电子伏特 = 伏特 × 库仑 / 1.602176565×10-19
或
eV = V × C / 1.602176565×10-19
What is the energy 中的 electron-volts that is consumed in an electrical circuit with voltage supply of 20 volts and charge flow of 2 coulombs
E = 20V × 2C / 1.602176565×10-19 = 2.4966×1020eV
