Transfer Functions: The RL Low Pass Filter
By Patrick Hoppe
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.
Electrical Generator Basics
By Terry Bartelt
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.
Excel: Rectangular to Polar Conversion for the Phase Angle in Radians
The conversion from rectangular to polar mode phase angle in radians is demonstrated in Excel.
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.
