Learners are introduced to primary and secondary batteries. Examples are given.
By Terry Bartelt
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Converting Values in Engineering Notation
By Ron Wallberg
The learner will convert various values to engineering notation.
The Induction Motor Slip
By Terry Bartelt, Terry Fleischman
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
Transistor Fundamentals: Decibel Gain, Power, and Voltage
By Patrick Hoppe
Students read about decibel power gain and decibel voltage gain. Examples are given for each.
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.
Voltage Sources in Series
In this learning activity you'll explore the effect of connecting voltage sources in series to increase voltage applied to a load.
