Learners examine first and second approximations and view examples of a "stiff" current source.
Crank Rocker Velocity
By James Bourassa
In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.
The 555 Monostable Multivibrator
By Terry Bartelt
Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.
The Purge Level Measurement Method
In this animated object, learners examine how the purge pressure system is used to measure levels of material. A brief quiz completes the activity.
The Shunt Motor Open Field
In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.
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.
Eddy Current Demonstration
Learners view two animations that show the effects of eddy currents.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-30XIIS Calculator)
Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-36X Calculator)
Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.
Instantaneous Current Calculations of an Energizing RL Circuit (Using a TI-36X Calculator)
Learners view a sample of the keystrokes on a TI-36X calculator that are required to solve for the instantaneous current of an energizing RL circuit.
