In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Total Impedance of a Series Circuit Using Complex Numbers: Practice Problems
By Patrick Hoppe
Students solve six problems for series impedance using complex numbers. Immediate feedback is given.
The MOD 10 Counter
The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.
Endothermic vs. Exothermic Reactions
By Terry Bartelt
In this animated object, learners examine how the heating or cooling steps in a manufacturing process work to control a chemical reaction.
Bipolar Junction Transistor Vocabulary
Students read the terms associated with the Bipolar Junction Transistor (BJT) . They also view formulas for dc current and voltage.
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.
Work and Power Formulas
Grade 8 Physical Science
Properties of Exponents: Multiplication Rule - Set 2
You'll practice solving problems using the rule for multiplying powers with the same base.
I am using this object as a refresher course in calculating RPM and TORQUE.
This tool is easy to use and well explained.
