In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

This document is a visual and text description of left-hand thread cutting on a lathe.

In this interactive object, learners work 11 problems covering atomic structure, conductors, and insulators.

This project gives a drawing with steps to complete the activity.

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.

In this animated activity, learners view the input and output leads of a JK flip-flop. They also see how it functions in each mode of operation. A brief quiz completes the learning object.

In this animated activity, learners view how to clear and preset a flip-flop to store a logic 0 or a logic 1.

Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.

You'll be introduced to concepts relating to redundancy and fault tolerances as they're applied to hard drives.
