Sifooyinka jajabinta ee jabka wareega yar yar

Astaamaha tufashadajabka wareeggawaxaa loo qaybiyaa A, B, C, D, K, iwm., macnahoodana waa sidan soo socota:
Astaamaha kala-goynta Nooca A: hadda kala-goynta waa (2~3) Gudaha, oo ku habboon ilaalinta wareegyada elektiroonigga ah ee semiconductor-ka, khadadka cabbiraadda ee leh transformers-ka awoodda yar, ama nidaamyada leh khadad dhaadheer iyo kuwo hooseeya.wareegga gaabanhadda jira;
Astaamaha turunturada Nooca B: qulqulka turunturada waa (3~5) Gudaha, oo ku habboon nidaamyada qaybinta korontada guryaha, ilaalinta qalabka guryaha iyo ilaalinta badbaadada shakhsi ahaaneed;
Astaamaha turuntureynta nooca C: turuntureynta waa (5-10) In, oo ku habboon ilaalinta khadadka qaybinta korontada iyo khadadka nalalka iyo wareegyada matoorada oo leh hadda beddelka sare;
Astaamaha turuntureynta nooca D: turuntureynta waa (10-20) In, oo ku habboon ilaalinta qalabka leh turuntureynta sare, sida transformers-ka, waalka solenoid-ka, iwm.;
Astaamaha tufitaanka nooca K: Waxay leedahay 1.2 jeer oo ah qulqulka kulaylka ee tufitaanka iyo 8 ilaa 14 jeer oo ah heerka tufitaanka birlabta, kaas oo ku habboon ilaalintaqalabka wareegga mootadawaxayna leedahay awood sare oo ka hortagta shoogga hadda
