Students review logarithms as they pertain to electronics.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

Students read about decibel power gain and decibel voltage gain. Examples are given for each.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.

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.
