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

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

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
Free Electricity Electromagnetism Lightning
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

we call Electricity. Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy. It is actually a secondary energy source‚ also referred to as an energy carrier. That means that we get electricity from the conversion of other sources of energy‚ such as coal‚ nuclear‚ or solar energy. These are called primary sources. The energy sources we use to make electricity can be renewable or non-renewable‚ but electricity itself

“Today‚ the nuclear family performs an essential function in society” Functionalism is a consensus view that society is like the human body and couldn’t function without all its parts- Society is characterised by groups working together and widely agreeing on norms and values. They believe that society influences the individual‚ and the individual is less important‚ as long as society is running smoothly. It is also a Structuralist view‚ meaning the social structures (family; education; the media;

Importance of Ethics for human being in society As children‚ we were taught by our parents that it is wrong to lie‚ cheat‚ and steal. As we grow up and enter into the real world with some knowledge of right and wrong‚ we see‚ first hand‚ the importance of ethics as well as its complexity. The role of ethics in our society is very necessary because it has a large influence on today‚ as well as the future. We need to learn about good ethics because they guide our decisions‚ make us who we are‚
