near the uncharged one‚ it attracts all of the opposite charges closer to the charged object. When two materials are rubbed together (like a balloon and your hair)‚ one will lose electrons and one will accumulate them. Producing Static Electricity Sometimes the outer layer of the object has negatively-charged electrons and the atoms are rubbed off‚ producing atoms that have a positive charge. The balloon

which is an electrical resonant transformer circuit designed by Tesla in 1891. It is used to produce high-voltage‚ low-current‚ high frequency alternating-current electricity. Tesla arrived in the United States in 1884. At the age of 28‚ and by 1887 had filed for a series of patents that described everything necessary to generate electricity using alternating current‚(AC) He created the A/C electric motor‚ which was pretty much the generator in reverse‚ was his most practical invention. It fit into

experiment is investing how length of an object is affected be the resistance. The electrons move away from the individual atoms of the wire when there is a electricity flow. This will cause a decrease in the speed at which the electrons move which then in matter of time‚ the electrons eventually stop. When electrons move through a conductor‚ electricity flows‚ which illustrates the moving of electrons in the wire which collide with the ions in the metal. This then makes it more difficult for the current

they are neither attracted nor repelled from one another. Two bulbs connect in series - The more loads that are connected in series‚ the lower the current would be in the circuit Instrument (equipment) and static electricity - Instrument: hair and ballon - Static electricity – is an imbalance of electric charge on the surface of an object 31.

famous scientist‚ John Dalton‚ who became an inspiration to Joule as he aspired to become a scientist himself. James Prescott Joule is well known for his research and experiments involving electricity‚ heat and mechanical work. He sent his paper in 1840 entitled‚ On the Production of Heat by Voltaic Electricity to the Royal Society in London – a prestigious association of British scientists. They paid little attention to Joule’s paper‚ and only published a brief summary of it. Three years later

Named after French scientist Andre-Marie Ampere‚ amperes are a unit of measurement for determining the amount of electricity moving through a circuit. Ampere’s Law simply states that the magnetic field within a closed loop is proportional to the

The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by coal based steam power plants or nuclear power plants
