Full Wave Rectifier |All About Ac To Dc

Every electronics circuit needs DC source to be operated . Full wave rectifier or a battery is good source of DC Power. If we represent AC Voltage using time graph, then you can see voltage sign wave. You can see two half cycle. Upper part is called ‚ÄúPositive Half Cycle‚ÄĚ and ‚ÄúLower Part‚ÄĚ is called Negative Half Cycle. ¬†So it is called Alternate current.   Why Electronics Devices operates in DC not In A ...
