这些并联的发电机的电流会累积在一起，总电流达到 500 安培。
The current from these parallel generators will add up to make a total flow of 500 amperes.
当电流达到其峰值，磁场的作用也。
As the current reaches its peak value, the magnetic field does also.
在这种情况下，电流达到最大值所需的时间改变了。
In this case, the time necessary for the current to reach its maximum value is changed.
