Learners examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
Current and Voltage Parameters of Digital Circuitry (Screencast)
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
