Complex numbers, also known as imaginary numbers, are arranged on a twodimensional number plane. These twodimensional numbers have two components: a real component and an imaginary component. The imaginary component of a complex number is tagged with a letter i or j. Imaginary numbers are ideal for describing and analyzing the phaseangle aspects of ac circuits. This is why the tutorials and activities in this special section are relevant to electronics engineering technicians. There two important prerequisites:
