Imagine a DC power supply with an output socket interface that has three pins: positive, negative, and ground. Correspondingly, the load’s plug should also have three pins that correspond one-to-one with the power supply side to correctly obtain power supply. Note that there are three essential conditions that must be met: The first is that … Read more
