Depending on the size of the electrolytic capacitor, the multimeter's R×10, R×100, and R×1K gears are usually used for test and judgment. The red and black pens are connected to the negative electrode of the capacitor (before each test, the capacitor needs to be discharged), and the quality of the capacitor is judged by the yaw of the hands. If the hands quickly swing to the right and then slowly retreat to the left, the capacitor is generally good. If the hands are no longer swiveled after...

Solid-state lighting is rapidly becoming the most popular lighting option for a wide range of applications. Due to the US government's task of saving energy, incandescent lamps have been largely eliminated and are increasingly being replaced by light-emitting diode (LED) lamps. The reason is because LED lamps have a longer life (usually 25,000 hours) and can easily accommodate a variety of different socket and shape requirements. As the price of LED lights continues to decline and is becoming...
