This is a project that gives steps to complete the activity.

Students read an introduction to transformers that includes schematic symbols, turns ratios, mutual inductance, and the coefficient of coupling.

In this interactive object, learners read an explanation of the electrodes used for welding with the GMAW and FCAW processes. In two matching exercises, students test their knowledge of classification and specification numbers.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.

In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.

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

Learners view the operation of a full-wave rectifier which has two diodes.

In this screencast, learners examine the internal elements of a 555 IC and their operation.

Understand pseudocode structure of Inputs and Outputs, a vital component of programming computer and industrial applications.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
