伏瓦特安培转换计算器
计算电压、瓦数和安培数之间的电功率关系。输入任意两个值来计算第三个值。
使用方法：输入任意两个值（电压、瓦数或安培数），然后单击“计算”以查找第三个值。检查三相框以进行三相功率计算。
计算结果单相
电压计算：
-
功率计算：
-
电流强度计算：
-
使用的公式（单相）：
电压 (V) = 瓦数 (W) / 安培数 (A)
功率 (W) = 电压 (V) × 安培数 (A)
安培数 (A) = 瓦数 (W) / 电压 (V)
电压 (V) = 瓦数 (W) / 安培数 (A)
功率 (W) = 电压 (V) × 安培数 (A)
安培数 (A) = 瓦数 (W) / 电压 (V)
