Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
Dynamic Braking Circuits
By Terry Bartelt
In this animated activity, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.
Total Resistance of a Series-Parallel Circuit: Practice Problems 2
By Terry Bartelt, Terry Fleischman
Learners work practice problems to calculate the total resistance of a circuit. Feedback is provided.
Series Circuit Analysis Practice Problems: Circuit #6
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.
Feedback System Application
In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.
Manufacturing PPE Mini-Sim
By Excelsior College
This activity is a simulation that allows the learner to practice personal protective equipment tasks.
Job Tasks Three Phase Motor Overheating
In this simulation, the learner must perform a series of job tasks in the role of an electrical mechanical technician conducting maintenance operations.
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.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
The Magnetic Circuit
Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
