In this animated object, learners examine the ratio control method used in automation when two or more ingredients are mixed. A brief quiz completes the activity.
PLC Timer Instructions
Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.
The Three-Phase AC Generator
By Terry Fleischman
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.
Oscilloscope: DC Voltage Measurements
Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
By Glenn Sokolowski
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
The Basic Operation of a Diode
In this interactive and animated object, learners examine the operation of a semiconductor diode when it is forward and reverse biased. A brief quiz completes the activity.
The Zener Diode: Practice Problems
By Patrick Hoppe
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
