PHYSICS ESSAY HOW ELECTROSTATICS INFLUENCE OUR LIVES? INTRODUCTION We all are familiar with the term electricity which comes from batteries and which is used to light bulbs‚ buzzers‚ and other electrical devices. We also know that conductors are those objects which conduct electricity easily and insulators do not conduct electricity at all. This is basic knowledge but right now we are going into detail about electricity and static electricity. ELECTROSTATICS Many of us have this wrong concept

T or F: ESD is very dangerous to computer technicians. False. What does the acronym ESD stand for? Electrostatic Sensitive Device. In what conditions is ESD most likely to occur? It occurs in cold‚ dry conditions. With __________ ESD‚ the damage is permanent and is noticeable right away. Catastrophic. What are the similarities and differences of latent and upset ESD? Similarities: Even if the device is damaged‚ it will still pass initial testing. How can a PC technician protect

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching

Riley Jefferson Block 7/8 October 8th 2012 Electrostatic Gedanken Lab Group Gamma Objective: The objective of this lab is to determine the charge on a pith ball. Hypothesis: I fully believe that the charge of the pith ball will be positive. The formula I will use to prove this is Coulomb’s Law‚ (Fe=(k*q1*q2) / r²). ‘Fe’ is equal to the electrostatic force between the spheres‚ measured in Newton’s. It is also a vector quantity‚ and it’s in absolute value. Secondly‚ ‘k’ is equal to Coulomb’s

Electrostatics Lab Name: Bryan Michel Materials: Styrofoam cups Styrofoam plates PVC Pipe Fur Scotch Tape Procedures: You will be investigating charging object by friction. When you are asked to write your observations‚ please do so in a clear‚ complete manner. 1. Tape a piece of string to a Styrofoam cup and hang it from the edge of the desk so that it can move freely. Rub the outside of the cup with fur. Rub a PVC pipe with fur and bring it near the hanging cup.

Electrostatics Electrostatics is a part of physics is that the study and analysis of electricity‚ its properties and its applications. Electrostatics was discovered when an ancient Greek philosopher named Thales. In 600 B.C.‚ Thales learned that when he rubbed amber with fur‚ it would start to attract other lightweight objects such as feathers and dust which is now known as a process called triboelectrification. This is also how we got the word electricity‚ which comes from the Greek word‚ elektron
