Ihe atụ nke ajụjụ Galvanometer 1
1. Lee foto a! Mgbe ogidi ndịda batara na coil ahụ, agịga galvanometer na-aga...
A. aka nri wee gaa n'aka ekpe
B. ozugbo ahụ ruo efu
C. aka ekpe wee gaa n'aka nri
D. aka ekpe wee gaa efu

Tupu ị leba anya n'ihe a na-akọwa, ọ dị mkpa ka ị ghọta iwu aka nri. Gbatịa aka nri gị, mee ka mkpịsị aka ukwu gị kwụsie ike, ma tụgharịa mkpịsị aka anọ ndị ọzọ. Ọ bụrụ na mkpịsị aka ukwu ahụ na-atụ aka n'akụkụ ọkụ eletrik, mgbe ahụ ntụgharị nke mkpịsị aka anọ ndị ọzọ na-egosi ntụziaka nke ọkụ magnet. N'otu aka ahụ, ọ bụrụ na ntụgharị nke mkpịsị aka anọ ahụ na-egosi ntụziaka nke ọkụ eletrik, mgbe ahụ mkpịsị aka ukwu ahụ na-egosi ntụziaka nke ọkụ magnet ahụ.
Agịga galvanometer na-aga n'aka nri ma ọ bụrụ na ọkụ eletrik na-aga n'aka nri nke sekit ahụ, n'akụkụ nke ntụgharị elekere na agịga galvanometer na-aga n'aka ekpe ma ọ bụrụ na ọkụ eletrik na-aga n'aka ekpe nke sekit ahụ, n'akụkụ nke ntụgharị elekere.
Iwu Lenz kwuru na EMF nke e tinyere n'ime ya na-emepụta ọkụ eletrik nke ubi magnetik ya dị iche na ntụziaka nke mgbanwe flux. Ya mere, ọ bụrụ na ogwe ndịda nke magnet ahụ agbada n'ime coil, a na-emepụta ọkụ eletrik nke ubi magnetik ya dị iche na ntụziaka nke mmegharị magnet ahụ. Site na iji iwu aka nri, ka ubi magnetik ahụ wee gaa n'elu (otu ntụziaka ahụ dị ka mkpịsị aka ukwu), ọkụ eletrik nke e tinyere n'ime ya ga-asọga n'aka ekpe nke sekit ahụ, n'akụkụ aka ekpe (otu ntụziaka ahụ dị ka mkpịsị aka anọ nke aka nri).
Ọ bụrụ na ogidi ndịda nke magnet ahụ abanye wee pụọ ọzọ n'elu, ọkụ eletrik na-asọga n'aka ekpe nke sekit ahụ wee gaa n'aka nri nke sekit ahụ ka agịga galvanometer wee gbaga n'aka ekpe wee gaa n'aka nri.
Ma ọ bụrụ na ogidi ndịda nke magnet ahụ abanye na coil wee kwụsị, ọkụ eletrik ahụ na-asọga n'aka ekpe nke sekit ahụ wee kwụsị ka agịga galvanometer wee gbapụ gaa n'aka ekpe wee laghachi na efu.
Azịza ziri ezi bụ D.
