Cov lus qhia rau kev siv cov cuab yeej ib txwm siv rau kev hloov kho:
1. Tshem tawm qhov kev tawm tsam los ntawm lub thawv daj, thiab solder qhov kawg ntawm lub diode xaiv nyob rau hauv lub thawv liab mus rau b kawg thiab c kawg rau d kawg kom tshem tawm qhov kev tawm tsam ntawm series Circuit Court uas muaj cov diode thiab resistor.
2. Yog tias tus qauv diode yog IN4007, nws yuav tsum tau hloov mus rau IN5408.
