Parallel RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
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.
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.
In this learning activity you'll explore the operation of frequency division using several different types of counters.
Sine Wave Fundamentals
By Patrick Hoppe
Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.
An Introduction to the Digital Multimeter
In this learning activity you'll explore the functions and proper operation of a digital multimeter.
The DC Motor
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
Voltage Divider Rule Practice Problems
Learners review the VDR and work six problems. Immediate feedback is given.
