Students review logarithms as they pertain to electronics.
Mathematical Expression of an AC Sine Wave
By Patrick Hoppe
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
Retro-Reflective Optical Sensors
By Terry Bartelt
Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.
By Kaye Krueger
Learners view examples of devices that prevent mistakes from occurring.
By Terry Bartelt, Pat Jensen
In this learning activity, we’ll explore the impact of electric shock on the human body.
The Magnetron Ignition System
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
Transistor Fundamentals: Collector Saturation and Collector-Emitter Cutoff
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
Transistor Fundamentals: Base-Biased NPN Transistor
Students view a dc analysis of a base-biased NPN transistor.
Transistor Fundamentals: Emitter-Biased NPN Transistor
Students view a dc analysis of an emitter-biased NPN transistor.
You'll learn to identify antenna terms and concepts.
