In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.
In this interactive lesson, learners study examples of nouns that can be counted and nouns that cannot. They then identify whether a word is a "count" or a "noncount" noun in a practice exercise.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
In this animated and interactive object, learners study how a DC circuit, consisting of a diac, a capacitor, and two resistors, causes a light-emitting diode to turn on and off. A brief quiz completes the activity.
