Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.

Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.

In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

In this animated activity, learners examine why various materials are conductors, insulators, or resistors of current. A short quiz completes the learning object.

In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.

This animated object allows students to examine the four steps used to reduce a complex circuit to a simple series circuit.

The learner will represent very large and very small numbers in engineering notation.

The learner will explore basic human limitations that create barriers to critical thinking including selective thinking, false memories, and perceptual limitations.

In this learning activity, we’ll explore the impact of electric shock on the human body.

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 how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Students identify the enamel, cementum, cementoenamel junction, clinical crown, clinical root, and epithelial attachment of a tooth.

Students analyze the eight single variable Boolean theorems and their expressions.

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

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.

Students examine examples for calculation yield, throughput yield, rolled throughput yield, and payback, each of which is used to analyze process performance in a Six Sigma project.

In this interactive object, learners sort veterinary respiratory drugs into categories.

In this screencast, learners identify the parts of the cardiovascular system and examine blood flow.

In this learning activity you'll explore the history behind gage blocks.

In this learning activity, you'll identify the three types of sexual harassment.

Explore the different types of personal protective equipment, which protects you against workplace hazards

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

The purpose of this learning object is to introduce the learner to the different processes of science.

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