Students work practice problems to calculate the total resistance of a circuit. Feedback is provided.
The DC Motor
By Terry Bartelt
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
Powers of Ten: The Proper Use of Symbols
By Patrick Hoppe
Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.
The TI-83 Plus Calculator: Using the Exponent Function
This primer introduces the student to the proper use of the "EE" function to perform calculations on very large or very small numbers.
By John Casey, Terry Bartelt
In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
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.
