Students read a definition of Kirchhoff's Voltage Law and view examples of its use.
Parallel Inductance: Practice Problems
By Patrick Hoppe
Students work nine practice problems to determine the total inductance of a parallel circuit. Immediate feedback is given.
The Zener Diode: Practice Problems
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
By Terry Bartelt, Terry Fleischman
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
Series RL Circuit Practice Problems
By James Bourassa, John Rosz
Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
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
By Terry Bartelt
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.
