Re: Electronics?? Pag-usapan natin..
mga sir patulong ulit. bumili kasi ako ng red led. 1.7v nga ba ang isa nito? balak ko gumamit ng 4 led sa 12v na power supply. tapos balak ko din gumamit ng 8 led sa 12v power supply. ano pong resistor ang dapat kong gamitin?

kung 4 led's in series pwede na ang 270ohms.depende sir kung 8 led's in series mahina na ang ilaw nito sa 12vdc,kung mag parallel ka ng 4 led's per series pwede at kahit isang resistor lang na 220ohms ang gamitin mong current limiter.

Re: Electronics?? Pag-usapan natin..
kailangan mo ng circuit ng smps para sa mas mataas na boltahe para mapailaw ang 8 led na naka series.

Sa 8 leds mag series parallel na lang. .
