如何将焦耳 (J) 为单位的能量转换为 电压 为单位的 伏特 (V).
You can calculate volts from joules and coulombs, but you can't convert joules to volts s为单位的ce volt and joule units represent different quantities.
The voltage V 为单位的 伏特 (V) is equal to the energy E in joules (J), divided by the charge Q in coulombs (C):
V(V) = E(J) / Q(C)
因此
伏特 = 焦耳 / 库仑
或
V = J / C
一个电路的能量消耗为60焦耳，电荷流量为4库仑，求其电压供应
V = 60J / 4C = 15V
