jail guard or a correctional officer should be permitted or required to use a taser on an inmate. When tasers are being used and are in firing mode they can shoot to a distance of 21 feet. They are programmed to deploy five-second bursts of electricity‚ although the charge can be prolonged indefinitely if the operator’s finer remains on the trigger. The shock can be repeated countless times. Both probes contain a cartridge of compressed nitrogen that fire the probes‚ and which must be reloaded

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

Study Guide‚ Chapter 8: Production and Distribution of Electricity Essay Questions: 1. Where are the big electric power plants in your state and what type of fuel do they use1? What is the primary fuel source used overall in your state? Massachusetts hosts three liquefied natural gas import terminals‚ one at Everett and two offshore of Gloucester (my hometown). Massachusetts generated 68 percent of its electricity from natural gas and 11 percent from coal in 2011. http://www.eia

Electrical Current An electric current is a flow of electrical charge. When a metal conducts electricity‚ the charge is carried by electrons moving through the metal. Electrons are subatomic particles with a negative electrical charge. When a solution conducts electricity‚ the charge is carried by ions moving through the solution. Ions are atoms or small groups of atoms that have an electrical charge. Some ions have a negative charge and some have a positive charge. Citric Acid Citric acid is

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

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

Groundwater Use and Overuse The biggest reservoir of fresh‚ liquid water on earth is groundwater. There is more than 20 times as much water stored within the ground as in all the lakes and rivers combined. In many parts of the world‚ agricultural‚ industrial‚ and domestic water demands can only be met by pumping water out of the ground. As you’ll see in the diagram below‚ wells work only if they penetrate the water table - the name given to the subsurface boundary that separates saturated and

Introduction: Now-a-days electricity has become quite-common in the world. Everybody sees the wonderful work of electricity. The lights on the streets are lit by the electric current. Electric fans work in the court‚ high court and office-rooms. Trains and trams are run by the electric power. So‚ electricity is no longer a strange thing. Discovery of electricity: About six hundred years back the people of Asia Minor and Greece had a very crude idea of electricity. Next‚ the American Scientist

“IF THERE IS NO ELECTRICITY” To think of life without electricity is almost impossible today. Elec tricity provides all the comforts of life. We find ourselves completely helpless and feel its importance whenever power fails or when the sup ply is irregular. We curse the government for its failure to supply unin terrupted electric supply. In case of no electricity our life would be totally different. We will have to use earthen lamps‚ lantern or candle-light instead of electric bulbs and tubes

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
