You can calculate volts from electron-volts and elementary charge 或 coulombs, but you can't convert electron-volts to volts s中的ce electron-volt and volt units represent different quantities.
电压 V 中的 伏特(V) is equal to the energy E in electron-volts (eV), divided by the 电荷 Q 中的 elementary charge 或 proton/electron charge (e):
V(V) = E(eV) / Q(e)
The elementary charge is the 电荷 of 1 electron with the e symbol.
所以
伏特 = 电子伏特 / 基本电荷
或
V = eV / e
What is the voltage supply 中的 volts of an electrical circuit with energy consumption of 800 electron-volts and charge flow of 40 electron charges
V = 800eV / 40e = 20V
电压 V 中的 伏特(V) is equal to 1.602176565×10-19 times the energy E 中的 electron-volts (eV), divided by the electrical charge Q in coulombs (C):
V(V) = 1.602176565×10-19 × E(eV) / Q(C)
所以
伏特 = 1.602176565×10-19 × 电子伏特 / 库仑
或
V = 1.602176565×10-19 × eV / C
What is the voltage supply 中的 volts of an electrical circuit with energy consumption of 800 electron-volts and charge flow of 2 coulombs
V = 1.602176565×10-19 × 800eV / 2C = 6.4087×10-17V
