My Undergraduate Electrical Materials Assignment Collection

Note

This is a collection of my Electrical Materials course assignment during my undergraduate study at the Electrical Engineering Department of Udayana University, 2010. Some of my assignments were lost because some of them were handwritten and submitted but here are the surviving assignments that were recorded electronically. The purpose of this post apart from being a reference for students is for others who want to know what kind of assignments were given during my era.

Introduction to Electrical Insulation and an introduction for the general public who have not yet studied electricity

To study electrical insulation, it is better to know in advance how electricity flows and its properties. In an atom there are three kinds of charges. Positive, negative and neutral charges. positive charge is called “proton”, negative charge is called “electron” and neutral charge is called “neutron”. Similar charges (++,-) repel each other, different charges (+-) attract each other. Electricity is a flowing charge, in the salt bridge in chemistry, electricity can be generated because of the…
