Current electricity is of vital importance because it gave rise to the discovery of modern electric equipments. Static electricity apparently is of no use. However it serves the purpose of friction and helps in holding objects together. Most matters have an equal number of electrons and protons. However the objects which have more electrons in their outer most shell they are negatively charged. While the objects which have more protons in the outer most orbit are positively charged.Static Electricity
Static electricity is generated when an object containing excess of electrons transfers them to positively charged objects. As a result an electric field is emerged which causes the effects of repulsion or spark. Static electric charge is produced when two objects are rubbed together and pulled apart. Object which has excess of negative or positive charge produces static electricity. Electric current can be more simply described as flow of electrons.
Current electricity is measured in amperes. So far there is no specific unit for measuring static electricity. Current electricity requires a conductor so that the electrons can flow and travel easily. Copper wire is the most widely used form of a conductor. Current electricity can be generated in many ways. It can be generated with the simple chemical reaction taking place in a battery. Current electricity can also be generated from the electric generators.
Electric generators transform the various forms energy like chemical and mechanical energy into electric current. Electric current is further divided into two forms as direct current and alternate current. Direct current is the direct flow of electrons or a direct chemical reaction like the one taking place in battery. Whereas indirect current is one present in the electric sockets and plugs. Direct current is the one which can not be controlled or stopped or in which the ions move in one same direction. However the indirect current is the one whose circuit is further broken down into on and off phases or in which the electrically charged ions randomly move in opposite directions. Alternating current is used for transferring electricity to homes and buildings. Current electricity is a manufactured product. Because it generated from the energy sources like coal, oil, hydraulic pressure and many other sources. When we separate opposite charges static current is produced. However when the opposite charges flow or move in opposite direction electric current is produced.
Both forms of electricity produce power. Static electricity produces the power to hold objects. While current electricity generates the power to operate or run electric devices. Electric energy is the flow of electrons and protons, and static electricity and current electricity are the portions of electricity. Current electricity can be generated from various other energy sources such as nuclear energy, wind and water pressures etc. this electric current generated as a result has helped us improve our lifestyle. Electricity has made our lives easier. Our survival without the energy sources from which we generate electric current further has become impossible now. The transfer of electrons produces a small electric current every time they move. As mentioned earlier this current is of many uses. Static electric current can pass through only insulators only like plastic and rubber, while current electricity can travel through only conductors such as electric wires.Advertisement
