Students view the formulas to be used to convert a series impedance to a parallel impedance.
Waveforms of a Triac Circuit
By Terry Bartelt
Learners observe the waveforms in a circuit in which a triac controls the brightness of a lamp’s light. A brief quiz completes the activity.
Series-Parallel Circuit Analysis Practice Problems: Circuit 3
By Patrick Hoppe
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
The TI-83 Plus Calculator: Using the Reciprocal Function for Complex Numbers
Learners examine the correct method for calculating complex reciprocals. The solution for total impedance of a parallel circuit in rectangular form is shown.
In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.
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.
