Hello:
-★ 1. When the voltage of resistive loads, such as light bulbs and electric cookers, rises, the power of the same load will increase, and the current will definitely increase.
-★ 2. When the voltage of an inductive load such as a motor increases, its load mechanical force does not change, but the running current will decrease, which is one of the characteristics of motor drive.
-★ 3. Light-emitting diodes are nonlinear elements and are current-controlled. If the voltage rises, the current will greatly increase and burn out.
