What is Eddy Current According to Lenz’s law, a conducting loop when subjected to varying magnetic field gets an emf induced into it causing flow of current in a direction opposing the change causing it. The case goes similar to when instead of a conducting closed loop, the change in magnetic field through a conducting body, say a filament or a slab of magnetic material or non-magnetic material, causes currents to flow into its cross sections at appropriate closed paths. These currents are g

What is a Centrifugal Switch?A centrifugal switchis an electrical switch powered by the centrifugal force created by a rotating shaft. This centrifugal force is typically provided by a gasoline engine or electric motor. Centrifugal switches are designed to activate or deactivate the rotational speed of the shaft.How do Centrifugal Switches work?A centrifugal switch is an electrical switch normally found in signal phase induction motors and split-phase induction motors.This switch is used to prov

Introduction of Efficiency of TransformerTransformers form the most important link between supply systems and load. Transformer’s efficiency directly affects its performance and aging. The transformer’s efficiency, in general, is in the range of 95 – 99 %. For large power transformers with very low losses, the efficiency can be as high as 99.7%. The input and output measurements of a transformer are not done under loaded conditions as the wattmeter readings inevitably suffer errors of 1 – 2%. So
