Learners read about a process for sorting items in the workplace. "Sort" is the first of the five steps in 5S.

Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.

In this learning activity you'll review the information and images on lockout and tagout procedures.

Learners follow the seven steps involved in the lockout/tagout procedure. This activity has video content demonstrating the safety measures.

In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.

Students review the Voltage Divider Rule and work practice problems.

Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

In this screencast, students read about the stages of microbial dental plaque formation and the time it takes for each stage to occur.

In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.

Students read about decibel power gain and decibel voltage gain. Examples are given for each.

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

Learners review the VDR and work six problems. Immediate feedback is given.

The learner will understand how a zener diode maintains a constant voltage as the resistance values of a load change.

Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.

The student will read a mini-lecture explaining the organization stage in the perception process and will complete an activity.

Learners review Kirchhoff's Voltage Law and work six practice problems. Feedback is given.

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

Learners view a sample of the keystrokes from a TI-35X or 36X calculator that are required to solve for the instantaneous voltage of a charging RC circuit.

In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
