Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

This paper is mainly concentrated on : i) The most popular concept known as Tesla Theory‚ ii) The microwave power transmission(MPT) called Solar power satellite‚ and iii) The highly efficient fiber lasers for wireless power transmission. The output microwave power ranges from 50 W to 200 W at 2.45 GHz. KEYWORDS: Microwave Power transmission (MPT)

Life without electricity Imagine life without electricity‚ not just a brief power outage. We all know how inconvenient life becomes when our electricity is out for only a few hours. How hard it is to remember for that short period of time that the light switch will not produce instant light‚ the hair dryer will not immediately blow dry our hair‚ or that we can’t even run water into our homes. Our homes and lives have become so dependent on electricity it is really hard to imagine everything that

I found the concept on frequency distribution using Google and the search words “frequency distribution” at http://www.mathsisfun.com/data/frequency-distribution.html This website is geared towards younger people and therefore breaks down frequency distribution into very basic terms: values and their frequency (how often each value occurs). The website uses the example of a child’s soccer team and how many goals they scored in recent games. For the assignment this week‚ I have chosen to use the
