In this animated object, learners study the problems that develop if the scan time of a PLC is too slow.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

Learners apply the principles associated with Boyle’s Law.

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

In this animated and interactive object, learners identify the valves and chambers of the heart.

In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.

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

Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.
