The learner will represent very large and very small numbers in engineering notation.
By Terry Bartelt
Learners view animations showing methods of measuring the pH level of a solution using litmus paper and electronic instruments.
RPM of AC Motors
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
Deriving the Formulas of the Power Wheel
By Ron Wallberg
Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.
Interlocking Ladder Diagrams
Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.
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.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
How Current Requires Voltage
This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
