This activity is a simulation that allows the learner to practice personal protective equipment tasks.

Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.

In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.

In this learning activity you'll examine a stateful packet inspection firewall that keeps track of legitimate Internet service requests, also known as dynamic packet filtering.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

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.

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.

Review the concepts of safety for Welding

You'll practice identifying and explaining safe practices for grinding
