fjäder. READ MOREBrushless DC Motors are an important class of highly efficient electric motors. They are most frequently used in electric vehicles because of their high efficiency and high power density. They are also present in the small DC fans used in power supplies and CPU coolers. In order to discuss the Brushless DC Motor it is important to first have a basic understanding of the more common Brushed DC Motor which is present in many household items. The brushed DC motor consists of a rotor

D. C. Polarography * Introduction: - Polarography is a particular case of general electro analytical technique known as voltametry. These methods are used to study the decomposition and quantitative analysis of solution. Principle: - It is a rapid and accurate technique in which electrolysis of experimental solution is carried out by using one electrode of comparatively large surface area (i.e. non-polarisable electrode) and the other electrode having a very small area (polarisable electrode)
