Given recent LED technology improvements and the drive toward greater energy efficiency, the LED lighting industry—including general illumination from commercial refrigeration to outdoor area lighting ...

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
