### Electric Charge

The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions, and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative, with a value of &#8722;1 in atomic units. Together with atomic nuclei, electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from...

### Electric Charge

each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge &#8211; positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel each other. Pieces of matter...

### Electric Charge and Lab Report Assistant

they both have opposite charges so that is why they can attract each other. B. How many types of charge did you work with in this exercise? How do you know? * I worked on 2 charges because I worked with tapes that I charged in the desktop doing the same procidures just charging them with the desktop. And also the ruler that I also charged to be able to attract it to the tape but the ruler I attracted it with the rabbit fur. C. If a third type of charge existed, how would it...

### Electric Charge

HW 1 solutions Point Charge in One Dimension A point charge q1 = -3.5 μC is located at the origin of a co-ordinate system. Another point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12,x, the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2, Q1=-3.5μC, Q2=5.1 μC, and r=9.3 cm we get F=-18.57...

### Electric Charge Lab

Electric Charge Lab John Doe Physics 1130 Oct 26th, 2010 Objective In this lab we will investigate some properties of electric charge, conductors, and insulators using everyday objects. Theory A charged object is any object that has an excess of negative or positive charge. Most objects are neutrally charged and we don’t normally experience their charge properties. Rubbing objects together and transferring some charge from one to the other is one way to create charged objects. Like charges...

### Experiment to Determine the Presence of Electrostatic Charges

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...

### Behavior of Electrostatic Charges

﻿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...

### Overview of Neuron Structural and Functional Properties and Electric Circuit

Overview Of Neuron Structural and Functional Properties and Electric Circuit Parameter Models from a Cellular Perspective. Neurons serve the purpose of receiving signals coming from neighbouring neurons; they assimilate these signals, and generate nerve pulses. They then conduct and transmit these nerve pulses to other neurons which are capable of receiving them. Neurons are the structural constituents of the brain. Typically, neurons are five to six orders of magnitude slower than silicon logic...

### Types of Electric Charge

Ch.9.1 – Types of Electric Charge * Static electricity : static cling of clothes out of dryer; lightning; * Walk across carpet and touch get a shock touching metal doorknob – friction of shoes against carpet cause you acquire static electric charge * Static chargeelectric charge at rest, stays on and eventually discharged or lost to other objects/air * Discharge – remove excess static charge so the object is neutral * Static charge last long when air is dry * Electrostatics...
