Electrical Active and Passive Components
An active component in a circuit is a part that needs power to work. A passive component is a part that doesn’t need power to work.
Phase sequence and Polarity of Three Phase System
Phase sequence is the sequence in which the voltages in a three-phase system reach their peaks. Each phase-shifted by 120 degrees with respect to the other two.
