Describe the inverting op-amp configuration and calculate the circuit gain.
PLC Sourcing Input Modules
By Terry Bartelt
In this interactive and animated object, learners study how to wire field devices to a PLC sourcing input module. A brief quiz completes the activity.
The Time-of-Flight Flowmeter
Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.
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.
DC/AC I: Unit 8 Sample Exam
By Patrick Hoppe
Students answer five questions concerning magnetism.
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.
Bandwidth Capacity Techniques
By Dennis Fontaine, Terry Bartelt
In this learning activity you'll follow the process of converting digital data into a series of analog signals.
In this learning activity you'll explore bandwidth.
Resistor Color Code Practice
In this learning activity you'll build a resistor's color code based on the bands.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
Why does -5 * 0.1V = -5 and not -0.5?
