Essays on Electrical Discharge

1. Introduction

During early days people do physical work to complete a job. The physical work made by the people made them tired and people time gets wasted. Let us take a construction work. The construction works involves major labors to construct a building, in early days people spends major time to construct a building. The labors have to give more energy to construct the building. Some of the labors even sacrificed their life by accident case inside the building. But today’s technology makes sure that the construction of any type of building can be modeled and executed within a year. Labor also ...
