Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
In this object designed for instructional assistants, learners read about the laws that pertain to student school records. Three case studies are presented and learners write about how they would respond in these situations.
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.
Learners review Ohm's Law and then work 12 problems. 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.
Identify your self-awareness score. In this learning activity, you'll answer 24 questions that attempt to measure three factors relating to self-awareness: introspection, public self-consciousness, and social anxiety.
Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.
In this interactive game, learners answer 30 questions about early childhood education activities and skills. Up to three people can play on the game board at one time.
Interpreting Engineering Drawings: Common Abbreviations
In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
