In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.
Hydraulic Brake Valves
By Terry Bartelt
The operation of a hydraulic brake valve, including the internal components, is presented using animations.
The Three-Phase Motor Stator Field
In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.
The Differentiator Op Amp
In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.
TI-86 Scientific Calculator: The Simultaneous Equation Solver
By Patrick Hoppe
Students follow step-by-step instructions to learn how to use the SIMULT function on this scientific calculator.
By Terry Fleischman
In this learning activity you'll read the procedures for using the vertical function of an oscilloscope and view illustrations of waveforms.
Oscilloscope Coupling Switch
Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.
Electrical Opens and Shorts
By Terry Bartelt, David Schwid
In this animated activity, learners examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.
In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.
In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
