    A DC power supply is a device that maintains a stable voltage and current in the circuit, such as dry batteries, accumulators, DC generators, etc. The DC power supply has two electrodes, positive and negative. The potential of the positive electrode is high, and the potential of the negative electrode is low. When the two electrodes are connected to the circuit, a constant potential difference can be maintained between the two ends of the circuit, thus forming a circuit from the positive electrode to the negative electrode in the external circuit. A DC power supply is an energy conversion device that converts other forms of energy into electrical energy supply circuits to maintain a steady flow of current.
