변환 방법 전기 전압 의 볼트(V) to energy 의 electron-volts (eV).
You can calculate electron-volts from volts and elementary charge 또는 coulombs, but you can't convert volts to electron-volts s의ce volt and electron-volt units represent different quantities.
에너지 E 의 electron-volts (eV) is equal to the voltage V 의 볼트(V), times the 전기 전하 Q 의 elementary charge 또는 proton/electron charge (e):
E(eV) = V(V) × Q(e)
The elementary charge is the 전기 전하 of 1 electron with the e symbol.
따라서
전자볼트 = 볼트 × 기본 전하
또는
eV = V × e
What is the energy 의 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
에너지 E 의 electron-volts (eV) is equal to the voltage V in 볼트(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
따라서
전자볼트 = 볼트 × 쿨롱 / 1.602176565×10-19
또는
eV = V × C / 1.602176565×10-19
What is the energy 의 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
