Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.
By Terry Bartelt
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Applying the Motor Voltage
In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.
Learners examine the internal components of an optical encoder used in automated manufacturing applications. A brief quiz completes the animated activity.
The TI-86 Calculator: The Complex Conjugate
By Patrick Hoppe
Learners view the steps to find the complex conjugate of a number in polar form using a TI-86 calculator.
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
