In this animated object, learners examine the relationship between pressure and temperature in an air conditioning system.

In this animated activity, students view a step-by-step approach for how to connect an ammeter to a circuit. A brief quiz concludes the lesson.

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

In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied.

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.

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

In this interactive and animated object, learners examine Midtronics hand-held battery and charging system testers and view the operation of these testers in an automotive repair facility.

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

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.
