AC Single Phase Energy
Fred Mullen, P.E.
Overview
This
course introduces single phase, electrical power definitions and calculations.
Energy and power considerations are at the heart of determining electrical
operating costs. A basic knowledge of the relationships between the power
source and typical electrical loads enables the engineer to determine the energy
required by a load and the rate (power) at which it is delivered. An
introduction to the units, components and basics of ac circuits is presented on
the way to realizing the energy calculation objective.
The
material is mainly intended for the non electrical engineer who requires a basic
understanding of single phase electrical power systems. Electrical engineers
who have worked a considerable time in other areas will also find the course
useful.
The course material is presented in an intuitive and illustrative manner with
the equations presented without derivation. The material assumes skill in basic
trigonometry and vector addition and conversion between Cartesian and Polar
representations.
The
student must take a multiple-choice quiz consisting of twenty (20) questions at the end of
this course to obtain PDH credits.
