VA 到安培计算器

伏安 (VA) 到安培 (A) 计算器及计算方法。

输入相数、视在功率（伏安），电压和伏特电压，然后按计算按钮，

以获得电流和 amps:

S和gle phase VA转安培计算 formula

The 电流 I 和 amps is equal to the apparent power S in volt-amps, divided by the 电压 V in 伏特:

I_(A) = S_(VA) / V_(V)

The 电流 I 和 amps is equal to 1000 times the apparent power S in volt-amps, divided by the square root of 3 times the line to line 电压 V_L-L 和伏特:

I_(A) = S_(VA) / (3 × V_L-L(V) ) = S_(VA) / (3 × V_L-N(V) )
