Single-phase                              Depicted above is a very simple AC circuit. If the load resistor's power dissipation were...

Phase rotation Let's take the three-phase alternator design laid out earlier and watch what happens as the magnet rotates: The...

Motor Perhaps the most important benefit of polyphase AC power over single-phase is the design and operation of AC motors. As we studie...

  Triplen harmonics   In the last section, we saw how the 3rd harmonic and all of its integer multiples (collectively called  triplen h...

Ohmmeter Though mechanical ohmmeter (resistance meter) designs are rarely used today, having largely been superseded by digital instrum...

Kelvin (4-wire) resistance measurement Suppose we wished to measure the resistance of some component located a significant distance awa...
