Good visual for lecture
This made the AC sine Wave much more clear and I will use this for my welding students.
In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.
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.
Students read about Kirchhoff's Current Law and view examples of its application.
