In this animated activity, learners examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.

In this animated activity, learners follow a step-by-step approach for connecting a digital multimeter to measure resistance. A brief quiz completes the activity.

Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.

Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.

Learners examine the relationship of voltage, current, and resistance as it applies to vehicle electrical systems.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. A brief quiz completes the learning object.

In this animated object, learners examine how to establish an effective supply chain that builds customer loyalty.

Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.

The learner will examine different adapters and componants used with brake lathes when resurfacing brake drums and rotors.

In this animated learning object, students are introduced to standard procedures, pilot actions, and pilot callouts for C-172 critical phases of flight.

In this interactive object, learners experience how the three primary flight controls allow a pilot to determine the motion of the airplane during flight.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Students read a definition of Kirchhoff's Voltage Law and view examples of its use.

In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.

Students determine what happens to current flow in a series circuit when the resistance is changed. A brief quiz concludes the activity.

The learner follows a step-by-step procedure for testing a computer ground circuit.
