Re: Why a tester shows glow in rectified DC output
hello the output obtained is 12v (1 AMP current) due to this the tester glows...when after getting o/p from bridge rectifier the output should be fed into ics 7805 and 7812
so that a suitable and perfect filtered output of 12v and 5 volt is...
hii,,,
1-u acn use 5v supply but to connect with micro controller u should use a resister which will drop 5v to 3.3..
2-it will also do good if u supply 5v from a adapter and then drop the voltage by using suitable resisters.it works
