In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
Kirchhoff's Current Law
By Tim Tewalt, Patrick Hoppe
Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.
Automotive Electrical Systems: Ohm's LawPractice Problems #2
By Andrew Rinke, Patrick Hoppe
Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Synchronous Speed of an AC Motor
By Terry Bartelt
In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.
The Vortex Flowmeter
Learners view an animation showing the operation of a Vortex flowmeter that is used to measure flow in a process control system.
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.
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.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
