Nduzi Electrode Graphite

Electrọd graphite

A na-ejikarị elektrọd graphite eme ihe n'imepụta ígwè n'ọkụ ọkụ eletrik n'ihi na ha nwere ihe ndị dị ka ike eletrik dị elu.

Nkọwa

Ugbu a, elektrọd graphite bụ naanị ngwaahịa dịnụ nwere oke ike eletriki na ikike nke ịkwado oke okpomọkụ a na-emepụta n'ebe a na-achọ ihe. A na-eji ha eme ka ígwè dị ọcha n'ime ọkụ ladle na usoro ịgbaze ihe ndị ọzọ. Ndị a na-arụ ọrụ dị ka ndị na-eduzi ọkụ eletrik n'ime ọkụ, na-emepụta okpomọkụ zuru oke iji gbazee ígwè ndị a kpụkọrọ akpụkọ, ígwè ma ọ bụ ihe ndị ọzọ e ji emepụta ígwè ma ọ bụ ọla ndị ọzọ. N'ime ọkụ nkịtị nke na-eji ọkụ alternating ma na-arụ ọrụ na ọnụọgụgụ nke usoro mmepụta kwa ụbọchị, otu n'ime elektrọd itoolu ahụ na-eri nke ọma (chọrọ ka etinye elektrọd ọhụrụ), na nkezi, kwa awa asatọ ruo iri ọrụ. Ọnụego oriri na mgbakwunye elektrọd maka ọkụ kpọmkwem dabere na arụmọrụ na mmepụta nke ọkụ ahụ.
