Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.
The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.
Compare the behaviors and situations that interfere with effective communication in the workplace with those that enhance listening skills and career performance.
Common Types of Oxidation-Reduction Reactions (Screencast)
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
Complex Power: The Sum of the Individual Real and Reactive Powers
The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
