Describe the inverting op-amp configuration and calculate the circuit gain.
Ignition System of a Combustion Engine
By Terry Bartelt
Students view the parts and movements of a combustion engine in this animated activity. Each part is described.
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
The Zener Diode: Practice Problems
By Patrick Hoppe
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
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.
