Rates & Calculations
This section of the Fundamentals of Electricity program will equip you with the knowledge to calculate the energy use and energy costs associated with any piece of electrical equipment, and will provide you with a full review of the various components typically found on a monthly electric bill.
You'll also learn how to calculate the more fundamental aspects of singlephase and threephase power  including voltage, current, impedance, wattage, and amperage  using key axioms such as Ohm's Law and Watts Law.
And finally, you'll learn the basic principles and formulas for calculating power factor and voltage drops.
