A complex number is a mathematical quantity representing two dimensions of magnitude and direction.
AC voltage or current in the form of a vector - The length of the vector represents the magnitude (or…
Vector Addition - If vectors with common angles are added, their magnitudes (lengths) add up just like regular scalar quantities.
If vectors with uncommon angles are added, their magnitudes (lengths) add up quite differently than that of scalar magnitudes.
Both polar and rectangular forms of notation for a complex number can be related graphically in the form of a…
Since complex numbers are legitimate mathematical entities, just like scalar numbers, they can be added, subtracted, multiplied, divided, squared, inverted,…
All the laws and rules of DC circuits apply to AC circuits, with the exception of power calculations (Joule's Law).
Polarity markings are sometimes given to AC voltages in circuit schematics in order to provide a frame of reference for…
