Conductors, Semi-conductors and Insulators

We rely heavily on the flow of electrical energy, even if it comes from solar power or the battery of our cars, to keep us informed and entertained. These chips and parts help run all of the gadgets and everyday items we take for granted -- that's what they have in common. Materials can be classified into: 1. Conductors 2. Semi-conductors 3. Insulators The main difference between these three types of materials is how well they conduct electricity, a property largely based on the arrangement of electrons around the nucleus of each atom involved. 1 . Conductors: In conductors, there are plenty of open spaces for electrons to jump from the shell of one atom to that of another. Electricity can steadily flow through conductors. Metals are the most common conductors we see, particularly copper. Others are silver, aluminum and gold. These conductors do a much better job of creating or maintaining electrical energy than semiconductors

Engineer - Definition

Engineers are scientists, mathematicians, inventors, and project planners combined. An engineer takes information from various fields and applies that information to solve problems. An engineer creates! An engineer is a force to be reckoned with! Essentially everything that you use in a given day was designed by engineers. From your computer monitor to your automobile, from your satellite radio to traffic lights, from your cell phone to the plane you fly in and the web browser you are using right now to read this article, artificial kidneys and heart-lung machines. All of these things are designed by engineers! Engineers create almost everything that society uses! Engineers invent solutions and products in every field, including disciplines like aerospace, software, biomedical, chemical, civil, mechanical, and electrical engineering. All engineers are given a similar basic education, but they also choose one of these specific disciplines to be trained in.
