Students complete a sample exam for DC/AC I. It provides an overview of the material presented in the course.
Capacitor Values (Screencast)
By Terry Bartelt
In this screencast, learners examine the physical facets that determine the value of a capacitor.
Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.
Sinking/Sourcing Input Modules
Learners examine the conventional current flow at a PLC input module, along with the field devices connected to it. This interactive object includes quiz questions and feedback.
Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Total Impedance of a Parallel Circuit Using Complex Numbers
By Patrick Hoppe
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
