The current lags behind the voltage.电流滞后于电压.If the input voltage is plus three , it comes out as minus six.如果输入的电压是+3伏, 那么输出的电压便是-6伏.The units in which we show voltage and current are volt and ampere respectively.我们用以表示电...
The torch can bring higher arc voltage with lower fluctuation by elongating the arc.该喷枪能够提高电弧电压并减小电弧电压波动.If the input voltage is plus three, it comes out as minus six.如果输入的电压是+3伏, 那么输出的电压便是-6伏。A high - voltage output fly...
