The Function Generator: Frequency Control
By Terry Bartelt
Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.
Parallel LC Circuit Tic-Tac-Toe 1
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.
Sine Wave Fundamentals: Practice Problem #2
By Patrick Hoppe
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
Photoelectric Reciprocation Circuits
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
Basic Terms in Division
By Barbara Laedtke
In this interactive object, the learner examines the basic terms used in division. A quiz completes the activity.
