LED

Recommended Posts

Salut , am vrut sa probez un led sa vad daca mai functioneaza si l-am conectat cateva secunde la o baterie de 9 V. A luminat putin dupa care nu a mai functionat , am mai incercat inca un led si aceeasi poveste , intrebarea mea e : S-a ars nu? trebuia sa pun si o rezistenta ca sa nu-l ard :|
