ELECTRICITY MR.ROBINSON Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects‚ such as lightning‚ static electricity‚ electromagnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. In electricity‚ charges produce electromagnetic fields which act

dependent on electricity‚ it seems‚ virtually‚ impossible to think if we can ever live without it. When an hour or so of load-shedding‚ especially on a hot summer day‚ can make us fret and fume and curse the whole system‚ what would happen‚ if this great boon is taken away from us forever? The whole life would come to a grinding halt‚ forcing all of us to experience the dull‚ dark‚ boring and uneventful period of the stone-age. As a matter of fact‚ to conceive of a life without electricity is‚ virtually

gas to generate electricity‚ and some use nuclear power‚ but there is an increasing use of cleaner renewable sources such as solar‚ wind‚ wave and hydroelectric. Types of power generating plants Electricity can be generated using the kinetic energy of water‚ heat energy of the sun and coal‚ or from the nuclear energy released from the fission of nuclear fuel. Nuclear Power Plants Nuclear power plants work on the chemical process of fission. Nuclear reactors are used to generate electricity. Fission

Electricity what is it? Electricity is also known as electrical energy which is the flow of moving electrons. Electrons are from atoms which have three different components with different charges. There are protons with a positive charge‚ neutrons with a neutral charge‚ and electrons with a negative charge. But the negatively charged electrons are useless if they don’t have a circuit to travel on. A circuit is a system that is made of three different components and they are: an energy source

There are a number of independent power producers that contributes significantly in electricity generation in Pakistan. For years‚ the matter of balancing Pakistan ’s supply against the demand for electricity has remained a largely unresolved matter. Pakistan faces a significant An Overview of Electricity Sector In Pakistan challenge in revamping its network responsible for the supply of electricity. Due to an unrealistic power tariff‚ high inefficiencies‚ low payment recovery and the

Lightning - Each bolt can contain up to one billion volts of electricity - Electrical discharge is caused by an imbalance between positive and negative charges in the atmosphere - Colliding particles of rain‚ ice‚ or snow increase this imbalance and often negatively charge the lower reaches of storm clouds - Objects on the ground‚ like steeples‚ trees‚ and the Earth itself‚ become positively charged - A step-like series of negative charges‚ called a stepped leader‚ works
