Pure Sine Wave Inverter Nrog 12v 24v

FT series: ntshiab sine yoj inverter nrog 12v 24v

Cov qauv thiab kev ua haujlwm ntawm photoresistor

Photoresistors, tseem hu ua lub teeb qhia, yog yuav luag tag nrho cov khoom siv optoelectronic ua los ntawm cov khoom siv semiconductor. Lub photoresistor tsis muaj polarity thiab yog cov khoom siv tiv thaiv, uas tuaj yeem siv nrog DC voltage lossis AC voltage. Thaum tsis muaj teeb pom kev zoo, tus nqi ntawm photoresistor (dub tsis kam) yog qhov loj, thiab tam sim no (tam sim no tsaus nti) hauv Circuit Court me me.

Thaum lub photoresistor raug rau lub teeb nyob rau hauv ib tug tej yam wavelength ntau yam, nws kuj (ci tsis kam) txo sharply, thiab tam sim no nyob rau hauv lub Circuit Court nce sai heev. Feem ntau, nws cia siab tias qhov loj dua qhov tsaus ntuj, qhov zoo dua, thiab qhov me dua qhov ci ci, qhov zoo dua. Lub sijhawm no, qhov rhiab heev ntawm photoresistor yog siab. Tus nqi tsis kam ntawm qhov tseeb photoresistor feem ntau yog nyob rau theem megohm, thiab qhov ci tsis kam yog qis dua ob peb txhiab ohms.  Daim duab 8-1 qhia lub hauv paus ntsiab lus ntawm photoresistor. Nws yog ib txheej nyias ntawm cov khoom siv semiconductor coated rau ntawm iav hauv qab phaj, ob qhov kawg ntawm lub semiconductor yog nruab nrog hlau electrodes, cov hlau electrodes txuas nrog cov hlau lead-tawm davhlau ya nyob twg, thiab cov photoresistor txuas nrog lub voj voog los ntawm cov hlau lead. - tawm terminal. Txhawm rau tiv thaiv kev cuam tshuam ntawm ib puag ncig nruab nrab, cov xim pleev xim rau ntawm cov txheej txheem semiconductor photosensitive, thiab cov xim ntawm cov xim yuav tsum ua kom qhov kev xa tawm siab tshaj plaws nyob rau hauv lub wavelength ntau yam uas cov txheej txheej photosensitive yog qhov rhiab tshaj plaws.
