    The existing load is a major factor in determining how much of a decrease in supply voltage a motor can handle (see sidebar, below). For example, let's look at a motor that carries a light load. If the voltage decreases, the current will increase in roughly the same proportion that the voltage decreases.

  • Chipload Calculator | GDP | GUHDO
