Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
By Terry Bartelt
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
Power Law Practice Problems #3
By Patrick Hoppe
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
AB SLC-500 Memory Structure
Learners examine the functions of the three types of memory used by an Allen-Bradley SLC-500 programmable logic controller: the Executive ROM, Scratch Pad, and Processor File.
Basic Elements of Dimensions Used in Engineering Drawings
By Glenn Sokolowski
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
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.
Series RL Circuit Vector and Circuit Analyzer
Parallel RC Circuit Vector and Circuit Analyzer
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.
You'll learn to identify antenna terms and concepts.
