Students read how to determine the elevation of an alignment or cross section where it crosses the TIN.

Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.

Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.

Learners answer eight questions about capacitors. Help pages are available.

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 lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

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.

Answer the questions correctly about themes, plot and mood.

In this game you will review the basic information of a Narrative paper. You will identify different sub-genres as well as the plot structure.

This game will help you remember the parts of a push mower.

You'll learn some concepts related to radio frequency modulation.
