Nkọwa Ngwaahịa

Waya ManganinA na-ejikarị ya eme ihe maka ngwa ọrụ voltaji dị ala nke nwere ihe kachasị mkpa, a ga-eme ka ihe mgbochi ndị ahụ guzosie ike nke ọma, okpomọkụ ojiji ekwesịghịkwa ịgafe +60 °C. Ịgafe okpomọkụ kachasị elu n'ikuku nwere ike ibute nguzogide nke sitere na oxidizing. Ya mere, nkwụsi ike ogologo oge nwere ike imetụta nsogbu. N'ihi ya, nguzogide yana oke okpomọkụ nke nguzogide eletriki nwere ike ịgbanwe ntakịrị. A na-ejikwa ya dị ka ihe nnọchi dị ọnụ ala maka ihe mgbakwunye ọlaọcha maka itinye ígwè siri ike.

Ngwa Manganin:

1; A na-eji ya eme ihe maka iguzogide ọnya waya nke ọma

2; Igbe ndị na-eguzogide

3; Ndị na-eme mkpọtụ makangwa nha eletriki

A na-eji foil na waya Manganin eme ihe n'imepụta resistors, ọkachasị ammetershunts, n'ihi na ọ fọrọ nke nta ka ọ bụrụ enweghị oke okpomọkụ nke uru iguzogide na nkwụsi ike ogologo oge. Ọtụtụ ihe mgbochi Manganin jere ozi dị ka ọkọlọtọ iwu maka ohm na United States site na 1901 ruo 1990. A na-ejikwa waya Manganin dị ka ihe na-eduzi eletriki na sistemụ cryogenic, na-ebelata mbufe okpomọkụ n'etiti isi ihe ndị chọrọ njikọ eletriki.

A na-ejikwa Manganin eme ihe n'ihe gbasara igwe ọkụ eletrik dị elu (dịka ndị sitere na mgbawa nke ihe mgbawa) n'ihi na ọ nwere obere mmetụta nrụgide mana ọ nwere nnukwu mmetụta nrụgide hydrostatic.
