Rov qab Biased PN Junction. Thaum lub davhlau ya nyob twg zoo ntawm qhov chaw hluav taws xob txuas nrog n-hom cheeb tsam thiab qhov chaw tsis zoo ntawm qhov chaw txuas nrog thaj tsam p-hom PN junction tau hais tias rov qab tsis ncaj ncees lawm. … Li no, PN kev sib tshuam yog dav.

Yuav ua li cas nyob rau hauv kev tsis ncaj ncees ntawm pn junction?

Kev thim rov qab ib qho hluav taws xob tau siv thoob plaws lub cuab yeej xws li hluav taws xob ntawm qhov sib txuas nceQhov hluav taws xob siab dua hauv cheeb tsam depletion txo qis qhov tshwm sim uas cov neeg nqa khoom tuaj yeem cuam tshuam los ntawm ib sab ntawm txoj kev sib tshuam mus rau lwm qhov, yog li qhov diffusion tam sim no txo qis.

Thaum PN kev sib tshuam yog thim rov qab?

Hint: P-n hlws ris yog hais tias yog nyob rau hauv kev tsis ncaj ncees lawm yog tias p-sab ntawm kev sib txuas yog txuas nrog lub davhlau ya nyob twg tsis zoo ntawm lub roj teeb thiab lub n sab txuas nrog rau sab tsis zoo. lub roj teeb.

Yuav ua li cas thaum diode rov qab biased?

Kev tsis ncaj ncees feem ntau yog hais txog yuav ua li cas lub diode siv hauv Circuit Court. Yog hais tias lub diode rov qab biased, qhov hluav taws xob ntawm lub cathode siab dua li ntawm qhov anode. Yog li ntawd, tsis muaj tam sim no yuav ntws mus txog rau thaum hluav taws xob hluav taws xob siab heev uas lub diode tawg.

Koj yuav paub li cas yog tias lub diode rov qab biased?

Thaum lub polarity ntawm lub roj teeb zoo li qhov uas tam sim no tso cai rau ntws los ntawm diode, lub diode tau hais tias yuav tsum tau ua ntej-kev coj ncaj ncees. Hloov pauv, thaum lub roj teeb "rov qab" thiab lub diode thaiv tam sim no, lub diode tau hais tias rov qab-biased.
