Difference Between Earthing, Grounding, and Neutral in Electrical Systems
Earthing, grounding, and neutral are often confused terms in electrical systems—but they serve different safety and functional purposes. While “grounding” and “earthing” are sometimes used
Energy Efficient Motors
Energy efficient motors are the most economical because these motors have higher efficiency than conventional motors like EFF-1 and EFF-2. Cost-effective production is the need
What is difference between AC and DC Resistance of a conductor?
AC resistance is higher than DC resistance due to skin and proximity effects. While DC current uses the full conductor cross-section, AC current flows near
