    Basic Principles Of Dc Power Supply

    The electrostatic field generated by the charge alone can not maintain a steady current, and by means of a DC power supply, the non-electrostatic effect (referred to as “non-electrostatic force”) can be used to make the positive charge from the lower potential Through the internal power back to the higher potential of the positive pole, in order to maintain the potential difference between the two electrodes, resulting in a steady current.
