Students view the formulas to be used to convert a series impedance to a parallel impedance.
Current Source Approximations
By Patrick Hoppe
Learners examine first and second approximations and view examples of a "stiff" current source.
Series-Opposing Zener Diodes
By Terry Bartelt
In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.
TPM: Total Productive Maintenance
By Kaye Krueger
Learners read how Total Productive Maintenance can prevent breakdowns, defects, and a variety of other losses.
RC Time Constant
By Tim Tewalt, Patrick Hoppe
In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
Inductive Reactance Practice Problems
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
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.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
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.
Cylinders: Basic Terminology
You'll practice defining terms relating to cylinders and identifying parts of cylinders.
