Static Electricity or Electrostatics Peter Jeschofnig‚ Ph.D. Version 42-0278-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions‚ diagrams if needed‚ and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports

Every single day we use electricity to make the things around us work. From the tape player to the electric pumps that send hot water to each of our homes everyday. Without electricity the lights go off‚ water is not heated‚ the television goes off‚ and outside the traffic lights do not work and as a result the city is immediately congested with traffic jams and choke ups in the street. Without that electricity we have everyday the basic things we use do not function. The book I chose to summarize

fixed and a floating charge has considerable significance particularly for the parties involved in commercial relationships. It follows from the fact that under English law a fixed charge has a priority over a floating charge that means the former will prevail over the latter even though the company has granted a floating charge to the creditor prior to the creation of a fixed security. Another reason is that under the provisions of Insolvency Act 1986 holders of a floating charge are placed in a less

Results and Discussion As there were five similar experiments done‚ there is one common observed behavior – similar charges repel and opposite charges attract. The experiment went expected as there were no unusual observations recorded. In the first part‚ it was observed that when the plastic rod was rubbed it attracted the tissue bits. The explanation with this is‚ when the plastic rod was rubbed‚ it became electrically charged. Conduction happens when the tissue paper was rubbed into the plastic

types of charges such as positive and negative charges. Like matter‚ charges cannot also be created or destroyed‚ but rather transferred from one object to another. Rubbing materials together is the easiest way in order to charge them wherein one object will become negatively charged and the other one will become positively charged. Electric charges can be characterized by repulsion between two positive charges or two negative charges‚ and can also be attraction between a positive charge and a negative

Rousselle Molina date submitted: 5/29/13 ELECTRIC FIELD MAPPING I. ABSTRACT: In the Electric Field Mapping‚ we used charged electrodes to create an electric field on a glass tray with a piece of linear graph paper attached to the bottom. We tested several simple electrode positions by moving the probes and drew equipotential lines based on the voltage difference. We then confirmed that the equipotential lines run perpendicular to electric field lines by looking at the experimental data

You rub balloons in your hair and then hang them like in the picture below. Explain why you think they move apart and what might affect how far apart they get. They move apart because they become charged while you are rubbing them in your hair and the charges are the same on both balloons. The more charges you get on the balloon the

Passenger Facility Charges While current HR 915 and S 1451 legislation has many impacts for airports and airport operations‚ none of the legislation would effect airports with such a dramatic change as the direct increase in the amount of passenger facility charges an airport is allowed to collect. Currently‚ Title 49‚ US Code section 40117‚ authorizes the Secretary of Transportation (further delegated to the Federal Aviation Administration Administrator) to approve the local imposition of an

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 law constant. The constant is equal to 8.99 * 10^9 N*m²/C². Thirdly‚ ‘q1’ is equal to the charge in Coulomb’s (C) of the
