Ungakala kanjani okuhle noma okubi ntombikayise?

1. Ukutholwa kwendlela eyodwa ye-SCR:

I-multimeter ikhetha ukumelana no-R * 1Ω, futhi umkhondo wokuhlola obomvu nomnyama usetshenziselwa ukukala ukumelana okuphambili nokubuyela emuva phakathi kwanoma iziphi izikhonkwane ezimbili kuze kutholakale izikhonkwane ezinokufundwa kwamashumi ama-ohms. Ngalesi sikhathi, iphini lomholi wokuhlola omnyama yi-electrode G yokulawula, Iphini yokuhola okubomvu i-cathode K, nenye iphini yamahhala i-anode A. Ngalesi sikhathi, xhuma isivivinyo esimnyama sokuhlola ku-anode ehluliwe A, nokuhlolwa okubomvu kuholela ku-cathode K.

Ukutholwa kwe-Triac:

Sebenzisa i-multimeter resistance R * 1Ω block, sebenzisa amapeni wamamitha abomvu namnyama ukukala ukumelana okuhle nokubi phakathi kwanoma yiziphi izikhonkwane ezimbili, futhi imiphumela yamasethi amabili okufundwayo ayinamkhawulo. Uma isethi eyodwa ingamashumi amashumi ama-ohms, izikhonkwane ezimbili ezixhunywe kusethi yamawashi abomvu namnyama yi-anode A1 yokuqala ne-electrode G yokulawula, futhi enye iphini yamahhala i-anode A2 yesibili.

Ngemuva kokunquma izingongolo ze-A1 nezika-G, linganisa ngokucophelela ukumelana okuhle nokuhlehlisa phakathi kwezigxobo ze-A1 nezika-G. Iphini elixhunywe kumthofu wokuhlolwa omnyama ngokufundwa okuncane kakhulu yi-anode A1 yokuqala, futhi iphini elixhunywe kumthofu wokuhlola obomvu yi-Control pole G.
