In this learning activity you'll build a resistor's color code based on the bands.
The Broadband Telco Services Subscriber Loop
Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.
Conductive Probe Sensors
By Terry Bartelt
In this animated object, learners study how conductive probe sensors are used to measure conductive liquid in a container.
In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.
Op Amp Fundamentals: The Transresistance Amplifier
By Patrick Hoppe
The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
Methods of Producing Electricity
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
What Is Color?
By Steve Utschig
In this animated and interactive lesson, learners examine additive and subtractive color theories.
Converting Between Gray and Binary Codes
Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.
Op Amps 3: The Inverting Amplifier
By Todd Van De Hey
Describe the inverting op-amp configuration and calculate the circuit gain.
This game will review primary, secondary, warm and cool color schemes.
