Students view the steps for dividing complex numbers in Excel.
RPM of AC Motors
By Terry Bartelt, Terry Fleischman
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
The Generation of Alternating Current
By Terry Bartelt
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
Average Voltages of Pulsating DC Voltages
In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.
Weight-Volume Relationships: Degree of Saturation
By Steve Whitmoyer
Students read how to determine and calculate the degree of saturation for a given sample of soil or aggregate based on the weight-volume relationship.
Basic Terms in Division
By Barbara Laedtke
In this interactive object, the learner examines the basic terms used in division. A quiz completes the activity.
Effects of a Rheostat in a Series Circuit
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
In this learning activity you'll explore the operation of frequency division using several different types of counters.
The TI-86 Scientific Calculator: Using Complex Numbers
By Patrick Hoppe
This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.
The TI-86 Scientific Calculator: Using the Reciprocal Function for Complex Numbers
This primer introduces the student to the correct method of using complex reciprocals in a TI-86 calculator. The solution of total impedance of a parallel circuit in rectangular form is shown.
