( is it the same as we have in music if yes, go on >> ) can we say in AC, zero crossing of current ( or voltage ) can cause harmonics ( some repeated waves with different frequencies? if yes, so what is harmonic in DC which we don't have any zero crossing!? I really want to know the concept of harmonic ( or harmonics!! or even harmony, which one ? ) in Electrical Engineering. I am electrical engineer but i still have problem in this ( and many more ... ) Thanks what is harmonic, what is called harmonic exactly? ( is it the same as we have in music if yes, go on >> )
