- Electrical calculations - Expanded knowledge.
- Phasors / Symmetrical Components
- Phasors in AC Circuit Analysis Phasors are a very important mathematical concept used frequently for Alternating Current(AC) circuit analysis. The phasor is like a vector, it has magnitude and arrow direction.
- Symmetrical Components in Electrical Engineering The knowledge of symmetrical components is very useful for the study of unsymmetrical faults in three phase power networks. The concept is also useful for studying the three phase machine behavior under unbalanced condition.
