Students complete a sample exam for DC/AC I. It provides an overview of the material presented in the course.
DC Circuit Analysis: The Series Circuit
By Patrick Hoppe
Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
Statics - Trig: The Pythagorean Theorem Using a TI-36XCalculator
By Steve Whitmoyer
In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.
By Terry Bartelt
Learners study animation showing the operation of an AC wound-rotor motor with its external starting resistors. A short quiz completes the activity.
Motor Control Circuits
Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.
