Students review logarithms as they pertain to electronics.
Oscilloscope AC Voltage Measurements
By Terry Bartelt
In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.
By Patrick Hoppe
Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

In this colorful and animated activity, learners examine the four functions provided by a hydraulic reservoir. A brief quiz completes the learning object.
Sizing Motor Overloads
By Terry Bartelt, Pat Jensen
Learners use the National Electrical Code to determine the size of a motor overload protection device.
The UJT Relaxation Oscillator
In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.
