Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

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.

Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.

Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

Students read how to determine and calculate the degree of saturation for a given sample of soil or aggregate based on the weight-volume relationship.

In this animated object, learners examine the operation of various circuits that are internal to the inductive proximity sensor.

Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.
