Ebe a na-ana chaja bụ egbe abụọỌdụ chaja DC, jiri modulu ike iri ejikọrọ n'otu oge, nke e ji ụdị njikwa chaja abụọ mee: ịchaji nha nhata na ịchaji nhata.

Ịchaji nha nhata: Ma egbe A na B na-ana n'otu oge, yana modulu ike ise kachasị na-ana site na egbe ọ bụla.

Ịchaji n'otu ebe: Mgbe naanị otu egbe na-arụ ọrụ, modulu ike iri kachasị nwere ike ịchaji.

Modulu ike ndị a na-enweta ntinye ike AC nke usoro atọ, ejikọtara ya na ihe nchebe ebili mmiri, mita ike AC nke usoro atọ, na ihe kọntaktị AC. Modulu ike ndị a na-ewepụta ike DC.
