Learners examine how a PLC Timer-Off instruction is used in the operation of an automotive paint booth.
The Transistor Symbol
By Terry Bartelt
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
Transistor Fundamentals: AC Model Equations
By Patrick Hoppe
Students view the equations used to determine the ac parameters of the transistor circuit.
Power Factor Correction 1
Students read an explanation of power factor correction. Examples of both inductive and capacitive loads are given.
Sine Wave Fundamentals: Practice Problem #8
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.
By Rosie Bunnow
Learners practice revising poorly written directions by applying criteria for giving directions.
The schematic symbols of logic gates used in digital circuits are shown.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Sequencer Output Instruction for the SLC-500 PLC
By Craig Hemken
Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.
The Universal NAND Gate 2
In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.
Use the arrow keys to direct the snake towards the type of logical fallacy in the example sentences.
