Transcript of Static Electricity

Static Electricity
Impact
Static electricity has several uses, also called applications, in the real world. One main use is in printers and photocopiers where static electric charges attract the ink, or toner, to the paper. Other uses include paint sprayers, air filters, and dust removal.

Alternative Energy
Current electricity is said to have a stronger purpose than static electricity. Static electricity is apparently of no use besides serving the purpose of friction and holding objects together.
History
In the Greek age, Thales found static electricity when he was cleaning his amber.But at that time, they did not pay attention to this and research it.
Math
Coulomb's Law of Electric Force:


This report proved that the electricity made by using a magnet, voltaic electricity produced by a battery, and static electricity are all the same. Since Faraday's result, the history of static electricity can be thought as the study of electricity in general. It is one of many types of electricity.
They just knew that rubbing something made a pulling force.Research into static electricity started in the 17th century. Otto van Geuricke made the first friction generator.
And in the 18th century, Coulomb started research into a fixed quantity of static electricity. Benjamin Franklin associated static electricity with storms. In 1832 Michael Faraday published the results of his experiment on the identity of electricity.
As stated earlier, in the 18th century, Coulomb researched into the topic of static electricity.
The following information explains about Coulomb's equation that he used for his law of electric force which is similar to electric power.
Electric power is the rate at which electric energy is transferred by an electric circuit. Electric power is usually produced by electric generators, but can also be supplied by electric sources like an electric battery.
Coulomb's law of electric force expresses the relationship in the form of the following equation:
P=VI
This equation is measured in the unit of watts. The P represents electric power. The V represents the voltage and the I represents the current.
P=VI
Although there are positive effects to static electricity, there are negative effects as well.
Static electricity can also cause damage. Some electronic chips, like the kind that are in computers, are very sensitive to static electricity. There are special bags to store these in. Also, people that work with these kind of electronics wear special straps that keep them "grounded" so they won't build up charge and ruin the electronic components.
Negative impact of Static Electricity
A spark of static electricity can measure thousands of volts, but has very little current and lasts for a short period of time. This means it has little power or energy.
Lightning is a powerful and dangerous example of static electricity.
As dangerous as lighting is, around 70% of people struck by lightning survive.
Temperatures in a lightning bolt can hit 50,000 degrees Fahrenheit.
Static electricity will be worse on a dry non-humid day.
Most matters have an equal number of protons and electrons.
Current electricity is of more importance and an alternate source of energy from static electricity because it helped develop the discovery of many modernly used electric equipments.
A spark of static electricity can measure up to three thousand (3,000) volts.
When you rub your socks on the carpet and touched someone, you just created static electricity. That spark is known as static electricity and it only last a few seconds. The static shock is caused by static electricity.
If you were to use the units in the formula, it would be:
Watts= Volts * Amps
Zhong Lin Wang has recently been developing a new nanogenerator. This will allow for cell phones to be charged just by using static electricity! When your mobile phone is in your pocket and you walk around, that little bit of friction, coupled with a new nanogenerator, produces enough static electricity to charge the battery, or even other devices, such as medical implants or hearing aids.
The new generator is made up of thin-film layers of plastic and metal, when flexed together, create a small electrical current. Nanoscale patterns on the films increase the surface area significantly, in the case of a one square centimeter [cm2], up to eight milliwatts. This is enough to power a pacemaker. A 25 cm2 piece of the same material is powerful enough to charge a mobile phone’s lithium-ion battery.
Overview
Dictionary Definition:
A stationary electric charge, typically produced by friction that causes sparks or crackling or the attraction of dust or hair.
The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
A static electric charge is created whenever two surfaces contact and separate, and at least one of the surfaces has a high resistance to electrical current (and is therefore an electrical insulator).
Change of Static Electricity
Over a large span of years, electricity discoveries have come a long way. Starting in 600 BC when Thales rubs amber with cat fur, up until most recently, in 1905, Albert Einstein completed Lorentz's work on space-time transformations and relativity was born.
Static Electricity makes your hair stand up and when it does, it is charged. Your hair tries to get as far away as they can.
Equations using P=VI
If you were given a unit of volts and amps, you would be able to figure out the number of watts.
Volts = 7
Amps = 8
To solve this, you would plug in those numbers into the formula, so 7 would be multiplied by 8.
Therefore, your watts, or P value, would be 56.
You may be wondering, what if you were given your P and V value and had to figure out the I value?
First, you would write out your equation with the numbers you were given.
P = 50
V = 5
50=5*I
To solve this, you would divide each side of the "=" by 5.
50/5 = I
10=I
Also, the same case would go if you had to find the V value, you would still just divide by the I value on both sides of the equation.
