Kev txiav txim siab qhov polarity ntawm semiconductor diodes los ntawm kev siv qhov muag saib: Feem ntau, cov ncej zoo thiab qhov tsis zoo ntawm qhov hluav taws xob semiconductor diodes tuaj yeem pom ncaj qha los ntawm lub qhov muag nyob hauv daim duab hluav taws xob tiag tiag.
Qhov tseeb tiag, yog tias koj pom cov xim ntawm ib kawg yog qhov tsis zoo electrode, lwm kawg yog qhov zoo electrode.
