Ledica na 230 VAC
izvinite što moram otvoriti novu temu za ovo iako je već jedna zaklučana.
našao sam nešto dijelova pa sam mislio to napraviti ali sam malo preoblikovao shemu:
Da li je ova shema ispravna, što vi mislite ???

Re: Ledica na 230 VAC
imas kondezator od 0,47uF i otpornik od 1K, i 2 ledice. i sta ne mozes naci?
Re: Ledica na 230 VAC
mislim da sam skužio šta me je cijelo vrijeme zezalo, krivo sam mislio.
- Manji kapacitet kondezatora to je otpor veći (obrnuto proporcionalno)

Re: Ledica na 230 VAC
Da li smijem staviti strujni krug sastavljen od samo: LED-ice i kondezatora, jer on je poput otpornika

Re: Ledica na 230 VAC
ne moze, moras imati i led ili diodu u suprotnom smeru, da bi kroz kondezator prolazila naizmenicna struja.
bez otpora ne moze, jer u pocetku kada je kondezator prazan nema sta da ogranici struju....

Re: Ledica na 230 VAC
tako na onoj stranici ima otpornik od 2,2 K spojen u seriju s kondezatorom iako ledica ima svoj otpornik, pa smatram da se njega može izbaciti, kako bi mi izgledao na kraju taj spoj ledice na 230 vAC

Re: Ledica na 230 VAC
ovako nekako:
ac source - kond 300v 0.27uF - katoda jedne ledice - anoda druge ledice
ac source - otpornik 2k 1W - anoda jedne ledice - katoda druge ledice
