1750 awesome technical articles
Hi, I'm an electrical engineer, programmer and founder of EEP - Electrical Engineering Portal. I worked twelve years at Schneider Electric in the position of technical support for low- and medium-voltage projects and the design of busbar trunking systems.
I'm highly specialized in the design of LV/MV switchgear and low-voltage, high-power busbar trunking (<6300A) in substations, commercial buildings and industry facilities. I'm also a professional in AutoCAD programming.

The basics of power in alternating current circuits (you MUST NEVER forget)
In a DC circuit, the power is equal to the voltage times the current, or P=V×I. This is also true in an AC circuit when the alternating current and voltage are in phase. That is, when the circuit is resistive…. Read more
