ʻO ka uea manganina he akeleawe-manganese-nickel alloy (CuMnNi alloy) no ka hoʻohana ʻana i ka lumi wela. Hōʻike ʻia ka alloy e ka haʻahaʻa haʻahaʻa haʻahaʻa electromotive ikaika (emf) i hoʻohālikelike ʻia mekeleawe.
Hoʻohana maʻamau ka uea Manganin no ka hana ʻana i nā kūlana kū'ē, nā mea pale ʻeha uea pololei, potentiometers, shunts a me nā mea uila a me nā mea uila.

ʻO ka uea Manganin (ʻo ka uea cupro-manganese) he inoa inoa inoa no ka huila o 86% keleawe, 12% manganese, a me 2-5% nickel.
Hoʻohana ʻia ka uea Manganin a me ka foil i ka hana ʻana i ka resistor, ʻoi aku ka ammeter shunts, no ka mea, ʻoi aku ka nui o ka mahana o ka waiwai resintance a me ke kūpaʻa lōʻihi.

Ka hoohana ana o Manganin

Hoʻohana ʻia ʻo Manganin foil a me ka uea i ka hana ʻana i ka resistor, ʻoi aku ka nui o ka ammeter shunt, no ka mea, ʻaʻole kokoke loa i ka helu ʻana o ka waiwai kūʻē a me ke kūpaʻa lōʻihi.
