Njirimara Anụ Ahụ nke Constantan

Waya ọla kọpa nickel alloy constantan, nke nwere obere iguzogide ọkụ eletrik, ezigbo iguzogide okpomọkụ na iguzogide nchara, dị mfe nhazi na ịgbado ọkụ lead. A na-eji ya eme ihe ndị bụ isi na relay okpomọkụ, obere ihe mgbochi okpomọkụ, na ngwa eletriki. Ọ bụkwa ihe dị mkpa maka eriri ọkụ eletrik. Ọ yiri nke cupronickel ụdị.

Njirimara anụ ahụ nke constantan bụ:
