A photocell yog tus resistor uas hloov qhov tsis kam nyob ntawm seb qhov teeb meem ntawm lub teeb ntawm nws. Lub photocell ua haujlwm ntawm semiconductor photoconductivity: lub zog ntawm photons tsoo lub semiconductor frees electrons ntws, txo qhov tsis kam.
Qhov twg yog qhov zoo tshaj plaws txhais ntawm photocell?
photocell in American English
(ˈfoutouˌsel) noun. Electronics . cov khoom siv hauv lub xeev uas hloov lub teeb rau hauv hluav taws xob los ntawm kev tsim hluav taws xob, xws li nyob rau hauv lub cell photovoltaic, los yog siv lub teeb los tswj cov ntws ntawm tam sim no, xws li nyob rau hauv photoconductive cell: siv nyob rau hauv Tsis siv neeg tswj lub qhov rooj, teeb pom kev zoo, thiab lwm yam.
Photocell Chav Kawm 12 yog dab tsi?
Hint: Ib lub xovtooj ntawm tes uas tseem hu ua Lub Qhov Muag Hluav Taws Xob, Photocell, lossis Phototube, yog ib lub raj hluav taws xob nrog lub cathode photosensitive uas yog emitting electrons thaum nws yog illuminated thiab anode rau sau. cov emitted electrons.
Vim li cas thiaj siv photocell?
Siv rau cov duab teeb pom kev zoo, tsis siv neeg ntawm-thaum tsaus ntuj txoj kev teeb thiab lwm yam kev siv teeb pom kev zoo, lub photocell nws txawv ntawm nws ob lub davhlau ya nyob twg raws li tus nqi ntawm photons (lub teeb) nws txais. Kuj hu ua "photodetector," "photoresistor" thiab "light dependent resistor" (LDR).
Tus yam ntxwv ntawm photocell yog dab tsi?
Cov yam ntxwv tseem ceeb ntawm photocell yog: Open- circuit voltage, Voc. Qhov ntawd yog qhov voltage uas tsim los ntawm lub xov tooj ntawm tes terminals thaum cov no tsis muaj hluav taws xob txuas ('qhib'): Qhov kev tiv thaiv (R) ntawm cov terminals yog infinitely loj, tsis muaj tam sim no (I) ntws ntawm lawv.
