Walxaha kululaynta Foornada waa gariiradaha ku yaal xagga sare iyo hoose ee foornada korontada ku shaqeysa oo kululeeya oo dhalaalaya marka aad shidto. Haddii foornadaadu aysan shidnayn, ama aad dhibaato kala kulanto heerkulka foornada inta aad karinayso, dhibaatadu waxay noqon kartaa dhibaato ku saabsan curiyaha kululaynta foornada. Isticmaal multimeter si aad u tijaabiso sii socoshada kuleyliyaha foornada si aad u ogaato in kuleyliyuhu si sax ah u shaqeynayo. Tani waxay qiimeyn kartaa in curiyuhu si sax ah u helayo calaamadaha korontada foornada. Tijaabooyinka kale ee aasaasiga ah waxaa ka mid ah hubinta gariiradda iyo hubinta heerkulka iyadoo la adeegsanayo heerkulbeegga foornada.
1. Foornada ka fur korontada, ka qaad qaybta kululaynta foornada, tijaabi oo qiimee sii socoshada kuleyliyaha foornada adigoo isticmaalaya multimeter, waxayna kuu sheegi doontaa in qalabka kuleyliyuhu shaqeynayo iyo in kale.
2 Go'aami tuubada kululaynta foornada ee ku taal xagga sare iyo xagga hoose ee foornada. Qaybta kuleylintu waa gariirad weyn oo ku taal xagga sare iyo xagga hoose ee foornada. Fur albaabka foornada, ka saar meesha birta ah oo ka saar tuubada kululaynta foornada.
Tuubooyinka kululaynta foornada waxay ku yimaadaan qaabab iyo cabbirro kala duwan, laakiin tallaabooyinka guud waa isku mid iyadoon loo eegin nooca ama nooca aad tahay. Marka foornada la damiyo, qaybta kuleyliyuhu waa madow ama cawl. Marka foornada la shido, walxahani waxay iftiimaan oranji.
3. Deji garaaca mitirka badan-ka ah dejinta ohm-ka ugu hooseeya (Ω). Geli fiilada cas godka cas iyo fiilada madow godka madow ee dusha sare ee mitirka badan-ka ah. Daar qalabka. Kadib, rog garaaca mitirka badan-ka ah si loogu dejiyo ohm, kaas oo ah cutubka cabbirka loo isticmaalo in lagu cabbiro iska caabbinta. Isticmaal lambarka ugu hooseeya ee laga heli karo heerka ohm-ka si aad u tijaabiso walxahaaga kuleyliyaha. (Beddel iska caabbinta u dhiganta iyadoo loo eegayo danabka iyo awoodda kuleyliyaha foornada).
Haddii aad xiisaynayso qalabka kululaynta foornada, fadlan si toos ah noola soo xiriir!
