Electric motor

Electric motor Electric motor, any of a class of devices that convert electrical energy to mechanical energy, usually by employing electromagnetic phenomena.  Most electric motors develop their mechanical torque by the interaction of Conductors carrying current in a direction at right angles to a Magnetic Field. The various types of electric motor differ in the … Read more

Electric Generators

working principle and use of Generator Generator is a machine that converts mechanical energy into electrical energy. It works based on principle of faraday law of electromagnetic induction. The faradays law states that whenever a conductor is placed in a varying Magnetic Field, EMF is induced and this induced EMF is equal to the rate … Read more

Corrosion and its prevention

Corrosion is defined as an attack on a material as a result of chemical, frequently electrochemical reaction, with the surrounding medium. According to this definition, the term corrosion can be applied to all materials, including non-metals. But in practice, the word corrosion is mainly used in Conjunction with metallic materials. Why do metals corrode? Apart … Read more
