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 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.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.

In this animated object, learners view the keystrokes on a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a discharging RC circuit.

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

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

In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.

In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.

In this interactive object, learners read the characteristics of each stage of labor and delivery. They then identify the stages in a multiple-choice assessment.

Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.

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 animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Students view the keystrokes of a TI-30XIIS 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.

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

In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.

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