In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
Powers of Ten: The Proper Use of Symbols
By Patrick Hoppe
Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.
Basic DC Electrical Motor Construction
By Terry Bartelt
Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.
Shorts Affecting Current in a Series Circuit
In this learning activity you'll review how a short affects current flow and voltage in a series circuit.
In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
