Ọtụtụ ndị ahịa na-eche banyere harmonics, mgbe ahụ, ihe bụ harmonic, gịnị bụ ihe ọjọọ nke harmonic, ugbu a ka m nye gị ụfọdụ okwu mmeghe.
N'otu okwu, n'ime sistemu ọkụ eletrik, harmonic nke ugbu a ma ọ bụ voltaji waveform bụ ebili mmiri sinusoidal nke ugboro ya bụ ọnụọgụ integer nke ugboro dị mkpa.
Na USA, ugboro a bụ isi bụ 60Hz, mana na ahịa Europe na Asia, ọ nwere ike ịbụ 50Hz.Na usoro 60Hz nwere ike ịgụnye 2nd-order harmonics na 120Hz, 3rd-order at 180Hz, 5th-order at 300Hz, etc. Na a 50Hz usoro nwere ike ịgụnye 2nd-usoro harmonics na 100Hz, 3rd-usoro na 150Hz, 5th-usoro na 250Hz, wdg. Ejikọtara, ha na-ebuga mgbagha n'ozuzu ya na usoro ịgbagharị ugboro ugboro.
