Kev suav nrog ntawm diode nyob rau hauv Circuit Court hauv qhov tsis sib thooj polarity ua teeb meem luv luv Circuit Court lossis tsis ua haujlwm ntawm lwm yam. Hauv qhov no, lub rupture ntawm electrolytic capacitors tshwj xeeb tshaj yog. Thaum muaj kev tsis ntseeg, ua ntej soldering lub diode, nws yog qhov yuav tsum tau hais meej qhov chaw ntawm nws cov terminals.
Cov Lus Qhia

Qhov teeb meem yooj yim tshwm sim yog tias muaj cov cim ntawm diode lub cev. Nws muaj qhov sib npaug ntawm daim duab peb sab thiab ib ntu ncaj kab, tawm tsam qhov no daim duab peb sab abuts ib ntawm nws lub ces kaum. Ntawm diodes cim raws li tus txheej txheem tshiab, qhov kev tsim qauv no yog ntxiv, raws li nws tau, hla tawm - qhov tseem ceeb ntawm qhov no tsis hloov. Saib raws nraim li cas qhov kev tsim qauv tau hais txog kev sib raug zoo nrog cov diode terminals: ib qho uas ze rau daim duab peb sab sib raug rau lub anode, thiab ib qho uas ze rau kab ntu sib raug rau cathode.

Yog tias koj paub tseeb hom diode, thiab koj muaj phau ntawv qhia lossis phau ntawv qhia ntawm tes, koj tuaj yeem txiav txim siab qhov polarity zoo li no. Saib ntawm qhov twg ntawm cov pins ib qho taw tes (lossis ob peb lub ntsiab lus) lossis lub voj voog yuav tsum tau nyob. Qee zaum, los ntawm tus lej lossis xim ntawm cov teev, nws yog qhov ua tau ntxiv rau txiav txim siab daim ntawv ntsuas ntawm lub diode nyob rau hauv cov kab, thiab los ntawm nws, nyob rau hauv lem, qhov siab tshaj plaws voltage.

Yog hais tias lub diode tsis muaj kev tsim qauv txhua thiab txhua yam koj paub txog nws yog rau pem hauv ntej tam sim no thiab rov qab qhov hluav taws xob, txiav txim siab nws cov polarity raws li hauv qab no. Nqa ib qho ohmmeter (lossis ntau yam khoom siv uas muaj txoj haujlwm no). Txiav txim siab qhov polarity ntawm qhov voltage rau nws qhov teeb meem nyob rau hauv hom kev ntsuas tsis kam, siv lwm diode raws li kev siv, pinout ntawm uas paub. Tom qab ntawd, txuas cov kab xev los mus rau lub diode nyob hauv kev sim hauv kev sib txawv, txiav txim siab qhov chaw ntawm nws cov hluav taws xob los ntawm kev sib piv.

Nws yooj yim heev los siv kev sojntsuam tshwj xeeb los txiav txim rau pinout ntawm diodes. Siv ob lub roj teeb AA, ib qho LED, ib 1 kilo-ohm resistor thiab ob qhov khoom ntsuas. Txuas txhua feem hauv series, thiab txiav txim siab qhov polarity ntawm hloov ntawm lub diode sim, yog li ntawd thaum qhov ntsuas raug kaw, nws ci. Txuas lub diode nyob rau hauv kev kuaj sim rau qhov ua ntej rau hauv ib polarity, tom qab ntawd hauv lwm. Thaum LED teeb tawm, cov zis ntawm lub diode tig mus rau sab tsis zoo ntawm lub zog mov yog cathode.
