Students review the Voltage Divider Rule and work practice problems.
PLC Output Modules
By Terry Bartelt, Terry Fleischman
The learner will understand the operation and configuration of various types of PLC output modules and how they're used.
Graphical BJT/JFET Transistor Biasing
By Roger Brown
Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.
The 555 Monostable Multivibrator
By Terry Bartelt
Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.
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.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief 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.
