In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.
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.
In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
Learners consider the most common types of electromagnetic waves and the kinds of hardware used in a wireless network. A short quiz completes the activity.
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.
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.
