==DC Power Supply==
   −
The most basic function of a DC power supply is to provide a constant voltage to a device. “DC” stands for direct current; “AC” stands for alternating current. A DC power supply converts the alternating current from a wall outlet to a steady direct current through a system of transformers and filtering circuitry. We have a couple different models of DC power supplies in the Maker Hub—all of which will be able to supply 12 VDC for this electronics workbench certification.

The most basic function of a DC power supply is to provide a constant voltage to a device. “DC” stands for direct current; “AC” stands for alternating current. A 9V battery is an example of a DC voltage, and it will hold a constant 9 volts (at least until the battery starts to die). A 120V wall outlet is an example of an AC voltage, and it will fluctuate up and down from 120V to -120V and back to 120V over a set period of time. A DC power supply converts the alternating current from a wall outlet to a steady direct current through a system of transformers and filtering circuitry.
