WebSep 7, 2024 · The LED light band will pulsate to show battery level and indicate active charging. The LED light band colors correspond to the charge level ranging from red … WebMay 3, 2024 · When the LED is forward biased, the electrons in the n-region will cross the junction and recombine with the hole in the p-type material. These free electrons reside in the conduction band and hence at a higher energy level than the holes in the valance band. The electrons in the higher energy level (conduction band) will not stay for long time. crypto ballers
