Mfundo ya inductor yosungira mphamvu zamagetsi
Ntchito yaikulu ya inductance ndi kusunga alternating current (kusunga mphamvu yamagetsi mu mawonekedwe a magnetic field), koma sichikhoza kusunga panopa (chindunji chamakono chikhoza kudutsa mu coil inductor popanda cholepheretsa). Ntchito yayikulu ya capacitance ndikusunga Direct current (kusunga...Werengani zambiri -
Kuwala kwa LED sikukugwira ntchito koma kuli ndi malangizo okonza mphamvu
M'moyo wamakono, tikugwiritsa ntchito kwambiri nyali za LED monga kuunikira koyambirira. Ndiwopanda mphamvu, osakhalitsa, komanso osawononga chilengedwe, ndipo amagwiritsidwa ntchito kwambiri m'nyumba ndi m'malo ogulitsa. Komabe, tiyenera kuchita chiyani ngati nyali za LED siziwalanso?
