Students review logarithms as they pertain to electronics.
Series RL Circuit Practice Problems
By James Bourassa, John Rosz
Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
Fundamentals of a DC Motor
By Terry Bartelt, Terry Fleischman
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
Hydraulic Directional Control Valves
By Terry Bartelt
In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.
The Counter-Reset Function
Learners examine the counter-reset function of a programmable controller and how it is used.
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
By Patrick Hoppe
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.
