Learners study animation showing the operation of an AC wound-rotor motor with its external starting resistors. A short quiz completes the activity.

Learners read an introduction of scalar quantity and vector quantity and force. Examples are given.

In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

The learner will convert various values to engineering notation.

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

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

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.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.
