In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
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.
Standard Transmission Signals
Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.
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.
Total Impedance of a Parallel Circuit Using Complex Numbers: Practice Problems
By Patrick Hoppe
Students work six practice problems to determine the total impedance of a parallel circuit.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Inductive Reactance Practice Problems
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Parallel RC Circuit Vector and Circuit Analyzer
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.
