In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Waveforms of a Triac Circuit
By Terry Bartelt
Learners observe the waveforms in a circuit in which a triac controls the brightness of a lamp’s light. A brief quiz completes the activity.
Sizing Motor Overloads
By Terry Bartelt, Pat Jensen
Learners use the National Electrical Code to determine the size of a motor overload protection device.
By Terry Bartelt, Terry Fleischman
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
The Time-of-Flight Flowmeter
Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
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.
The DC Shunt Motor
Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.
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.
Basic DC Electrical Motor Construction
Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.
Properties of Exponents: Multiplication Rule - Set 2
You'll practice solving problems using the rule for multiplying powers with the same base.
Work and Power Formulas
Grade 8 Physical Science
