10. Tambayoyi na Gama Gari Dangane da Ma'auni na Fasaha

Q: Wane ƙimar resistor ne ya kamata in yi amfani da shi tare da samar da wutar lantarki 5V don halin yanzu na tuƙi na 20mA?

A: Yin amfani da V na yau da kullun_fna 2.4V, ƙarfin wutar lantarki a kan resistor shine (5V - 2.4V) = 2.6V. Yin amfani da Dokar Ohm (R = V/I), R = 2.6V / 0.02A = 130 Ω. Daidaitaccen resistor 130 Ω ko 120 Ω zai dace, la'akari da ƙimar wutar lantarki (P = I²R = 0.0004 * 130 = 0.052W, don haka resistor 1/8W ko 1/10W ya isa).

Q: Zan iya tuƙa wannan LED a 30mA ci gaba?

A: Ee, 30mA shine matsakaicin ƙimar halin yanzu na gaba a 25°C. Koyaya, tabbatar an yi la'akari da yanayin yanayi, kamar yadda halin yanzu da aka yarda yana raguwa sama da 50°C.

Q: Me ya sa ƙaramin kusurwar kallo ke da fa'ida?

A: Ƙaramin kusurwar kallo (40°) yana tattara ƙarfin haske zuwa ƙaramin kusurwa mai ƙarfi. Wannan yana haifar da ƙarin ƙarfin haske na axis (candelas) idan aka duba shi kai tsaye, yana sa LED ya zama mai haske don aikace-aikacen nuni inda mai kallo yawanci yake daidaitawa da axis na LED.
