The schematic symbols of logic gates used in digital circuits are shown.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

Learners review Kirchhoff's Voltage Law and work six practice problems. Feedback is given.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

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.

Learners view two animations that show the effects of eddy currents.

Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.
