When you study electrical engineering technology (EET), you study the lifeblood of today's technology: electronics and computers. Electrical engineering technology is a part of virtually everything ...

Article 725 of the National Electrical Code (NEC) provides the requirements for “Class 1, Class 2, and Class 3 remote-control, signaling, and power-limited circuits.” The title of Art. 725 includes ...

Current transfers energy around circuits. Circuit components have various properties that can be measured and then used to make circuits for control and also circuits for testing other components.

In the last 150 years, engineers have developed and mastered ways to stabilize dynamic systems, without lag or overshoot, using what's known as control theory. Now, a team of University of Arizona ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Rule 1: Read first to learn how the circuit works, then redraw to troubleshoot. Rule 2: When tracing a circuit, always work from the load to the battery, or from negative to positive. Rule 1: Read ...

Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

To make something work using electricity there needs to be an electrical circuit; a circuit is a complete loop that electricity can move around. Electricity moves from the power source (the battery or ...
