Students view drawings of the emitter resistor bypass capacitor.
By Terry Bartelt
Learners study animation showing the operation of an AC wound-rotor motor with its external starting resistors. A short quiz completes the activity.
The TI-83 Plus Calculator: The Square Root Function
By Patrick Hoppe
Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.
RPM of AC Motors
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
Pulse Train Fundamentals: Practice Problem #3
In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.
Parallel RC 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.
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.
In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.
This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.
