In recent decades the increasing capabilities of thyristors has contributed to an ever expanding variety of new and popular electrical devices. Along with this use of thyristors there has been a widespread introduction of harmonics and nonlinear currents into electrical circuits. These harmonic currents cause distortions in the shape of currents and deviations from the preferred sinusoidal profile. At times there is a need to quantify the power associated with these nonlinear currents. Many wattmeters and watt-hour meters will not accurately measure power in a nonlinear circuit, so there is need at times for the computation of nonlinear power.
In linear circuits the voltages and currents may be readily described by sine wave functions. The computation of power is straightforward when the voltages and currents are in the shape of a sine wave. Not so in nonlinear circuits. This course outlines a method of calculating the power of nonlinear circuits.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
NY PE & PLS: You must choose courses that are technical in nature or related to matters of laws and ethics contributing to the health and welfare of the public. NY Board does not accept courses related to office management, risk management, leadership, marketing, accounting, financial planning, real estate, and basic CAD. Specific course topics that are on the borderline and are not acceptable by the NY Board have been noted under the course description on our website.
AIA Members: You must take the courses listed under the category "AIA/CES Registered Courses" if you want us to report your Learning Units (LUs) to AIA/CES. If you take courses not registered with AIA/CES, you need to report the earned Learning Units (not qualified for HSW credits) using Self Report Form provided by AIA/CES.
