Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

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.

In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.

The TI-83 Plus Calculator: Using the Reciprocal Function for Complex Numbers

Learners examine the correct method for calculating complex reciprocals. The solution for total impedance of a parallel circuit in rectangular form is shown.

In this animated and interactive object, learners examine how changes in applied voltage affect the current and voltages in a zener diode voltage regulation circuit. A short assessment completes the activity.

In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
