Tus pointer multimeter ntsuas qhov zoo ntawm photoresistor li cas?
Photoresistors, tseem hu ua lub teeb kav dej, feem ntau yog ua los ntawm cadmium sulfide, nrog rau selenium, txhuas sulfide, txhuas sulfide, thiab bismuth sulfide. Cov ntaub ntawv fabrication muaj cov yam ntxwv uas lawv cov nqi kuj txo qis sai nyob rau hauv lub irradiation ntawm lub teeb ntawm tej wavelength. Qhov no yog vim hais tias cov cab kuj tsim los ntawm lub teeb yog tag nrho cov koom tes nyob rau hauv conduction, drifting nyob rau hauv qhov kev txiav txim ntawm ib tug sab nraud hluav taws xob teb, cov electrons maj mus rau lub zoo ncej ntawm lub hwj chim mov, thiab lub qhov maj maj mus rau qhov tsis zoo ncej ntawm lub hwj chim mov, kom qhov tsis kam ntawm photoresistor poob sai.
Photoresistor yog ib qho tshwj xeeb resistor ua los ntawm cov khoom siv semiconductor xws li vulcanization lossis selenization. , nyob rau hauv ib puag ncig hnyav ntawm cov av noo, nws tseem tuaj yeem tswj tau qhov kev ruaj ntseg thiab kev ntseeg siab, thiab tuaj yeem siv dav hauv cov koob yees duab, hnub ci vaj teeb, teeb nyom, nyiaj ntes, quartz moos, khob suab paj nruag, thawv khoom plig, mini hmo teeb , lub teeb thiab suab keyboards, Txoj kev teeb tsis siv neeg hloov thiab ntau yam khoom ua si tswj lub teeb, tswj lub teeb pom kev zoo, teeb thiab lwm yam teeb pom kev tsis siv neeg hloov chaw.
Sensitive resistor cim sawv cev
Lub photoresistor yog lub teeb-sensitive tivthaiv uas nws tus nqi kuj tuaj yeem hloov nrog kev siv ntawm lub teeb sab nraud. Lub photoresistor yog sawv cev los ntawm tsab ntawv "R" lossis "RL" lossis "RG" hauv Circuit Court, thiab daim duab hauv qab no yog nws cov duab kos duab.
