In this animated activity, students view the operation of a 4-bit serial-in serial-out register. A brief quiz completes the learning object.

In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

In this learning activity you'll review the steps for calibrating the length of depth micrometer measuring rods.

In this learning activity, we’ll explore the impact of electric shock on the human body.

The explanation and use of timing diagrams used in digital electronics to graphically show the operation of various circuits are given.

In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.

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.

The learner will understand proper safe handling and installation procedures for shielding gas cylinders.

This document gives an overview of chuck maintenance.

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.

Students test their skill at converting binary numbers to decimal numbers. Immediate feedback is provided.

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

In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.

Learners practice reading prints of a hub. They identify information located on the print and calculate missing dimensions.

Learners will determine if they are satisfied with their attitudes and then rank tips for regaining a positive disposition in the workplace.

Learners will understand the technical terms used in the context of the SDS to help them interpret its information.

In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.

Students view how the tool length offsets are set on the CNC Machine. They read a description of a method that uses a 2-inch gage block as a height reference.

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.

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

In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

In this learning activity you'll review different types of steel rules used in manufacturing.

The learner will identify the advantages and disadvantages of the four modes of GMAW transfer.
