How does a DC power supply work?
280A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies. ,

How to read the measurement results of a digital multimeter?
361Most handheld or benchtop digital multimeters display measurements digitally. The number of digits displayed on the screen usually represents the measurement resolution of the digital multimeter. Resolution is the smallest detail that a digital multimeter can quantitatively determine when making a measurement. Therefore, the more digits a digital multimeter displays, the higher its resolution. Handheld digital multimeters are typically capable of displaying three-and-a-half and four...
