Current and Voltage Parameters of Digital Circuitry
By Patrick Hoppe
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
Mathematical Expression of an AC Sine Wave
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
Transfer Functions: The RL Low Pass Filter
Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
Total Impedance of a Series Circuit Using Complex Numbers
Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.
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.
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.
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.
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.
