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 ...

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 ...

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 ...

Control theory is the study of how one can use feedback to modify the behavior of a system — such as a robot, vehicle, chemical or biological process, power grid, stock portfolio, or an ecosystem — so ...

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 ...

To help achieve more precise control of gene therapy, engineers have designed a new control circuit that can keep gene expression levels within a target range. The method could be used to deliver ...

How do the circuits of the human brain work—and what happens when they are disrupted? To investigate these questions, ...

This video explains the function of inductors and how they store energy in a magnetic field when current flows through them. Inductors are essential passive components used to manage current changes ...
