In this interactive object, learners view a practical application of a PLC Timer-On function.
By Terry Bartelt, Stephen Schneider
Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
Automotive Electrical Systems: Ohm's LawPractice Problems #2
By Andrew Rinke, Patrick Hoppe
Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Parallel Circuit Analysis Practice Problems: Circuit #4
By Patrick Hoppe
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
Series-Parallel Circuit Analysis Practice Problems: Circuit 10
Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.
Financial Statement Analysis
By Lynette Teal
Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.
By Terry Bartelt
The schematic symbols of logic gates used in digital circuits are shown.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Instructions on how to use and construct a truth table for digital devices are provided.
Digital Circuit Devices
The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.
You'll focus on terminology related to designing a hypothetical program.
