Topic 7

Power in an AC Circuit

This series of videos run in sequence. First is the revision of the voltage triangle, then the impedance triangle, then the power triangle.
The lesson is mostly about the 5th video. However each video builds on the one before it.
- Quiz 7 Power
- Phasor Diagram for Inductive Load
- Power Triangle
- Calculating Power Factor
- Quadrature Power is also known as Reactive Power.
  Why is there no power being consumed?
Topic 8

Power Factor Improvement

This series of videos run in sequence. First is the revision of the effect of impedance as opposed to resistance. The next one looks at how to calculate the impedance of a coil, the resistance of a coil, the reactance of a coil, and the Inductance of a coil. The last video is about power factor and power factor correction.
The lesson is mostly about the last video. However each video builds on the one before it.
