Parallel Circuit Analysis Practice Problems Part 2
By Patrick Hoppe
In this interactive object, students work 11 practice problems and solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.
Overflow and Underflow for Signed Binary Numbers
By John Casey, Terry Bartelt, Terry Fleischman
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
BCD-to-Seven Segment Decoder
By Terry Bartelt, Terry Fleischman
Learners will understand how binary-coded decimal information is decoded and used to drive a seven-segment display.

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.
Oscilloscope Phase Shift Measurements
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
Parallel Circuit Analysis Practice Problems: Circuit #9
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
Total Resistance in a DC Parallel Circuit
In this learning activity you'll determine the total resistance in a DC parallel circuit.
Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.
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.
Students follow step-by-step directions on how to make mathematical calculations for a Wheatstone bridge.
Electrical Units, Abbreviations, and Symbols
In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.
The DC Motor
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.
Electrical Generator Basics
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
Sine Wave Fundamentals
Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.
Proportional Control Amplifier
Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
Voltage Divider Rule Practice Problems
Learners review the VDR and work six problems. Immediate feedback is given.
