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

The X-Ray imaging system has one function‚ and that is to provide a constant flow of electrons that are strong enough to produce and x-ray beam to create an image. There are many different sizes and types of imaging systems but no matter what system you use‚ every type will have three main sections. Those sections are the control console‚ the high voltage generator and the x-ray tube. The x-ray tube is located in the exam room‚ the control console is located in an adjoining room that is separated

CHAPTER 1 INTRODUCTION Now-a-days every institution needs automation. As a part of college automation‚ we have decided to do a project “voice interactive system for college automation”. Our project allows the user to know the student’s attendance and marks quickly through the telephone line without the intention of the college authority. In the hardware side embedded system has been used. The microcontroller controls the whole

The optimal M1‚2 width (W) is determined for several M1‚2 lengths (L) and bias current Ibias‚ and the overall optimal set of values is W=600µm‚ L=3µm‚ Ibias=53µA. Noise measurements show that 1/f noise has a slightly higher impact than does white noise‚ when both contributions are A-weighted. The expected SNR degradation introduced

Module 06 Case Study: Articulations and Nerve Tissue Part I— “Jill” Questions 1. What is the difference between a tendon and ligament? (1 point) --The difference between a tendon and a ligament is that a tendon attaches to muscle. (ie. muscle-bone‚ muscle-muscle‚ muscle- skin) A ligament‚ however‚ attaches to cartilage. (ie. cartilage-bone‚ cartilage-cartilage‚ bone-bone) 2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your
