Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.

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

Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.

In this interactive object, learners examine the PN sections of a diode and the diode's forward- and reverse-biased operations. A brief quiz completes the activity.

In this learning activity you'll create a packet filter.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.
