In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.
Parallel Capacitance: Practice Problems
By Patrick Hoppe
Learners solve six problems determining the total capacitance of a parallel circuit. Immediate feedback is provided.
Series-Parallel Circuit Analysis Practice Problems: Circuit #5
Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.
By Terry Bartelt
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Ohmmeter Capacitor Testing
Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.
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.
