In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
Ohmmeter Capacitor Testing
By Terry Bartelt
Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.
By Patrick Hoppe
In this learning activity you'll calculate the total inductance of a series circuit.
The TI-83 Plus Calculator: The Power Function
Learners examine how to raise a number to a power using the TI-83 Plus calculator. Sample problems are given using both real and complex numbers.
Temperature Emissivity of Non-Blackbodies
Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
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.
