interventions. Five major imperative scientific discoveries that have been made are electricity‚ vaccination‚ computers‚ motor vehicles and the telephone. Electricity was not discovered by one scientist‚ but by various scientists who built on the knowledge they have of it. These were scientist such as Benjamin Franklin‚ Alessandro Volta‚ Michael Faraday‚ Thomas Edison and George Westinghouse. Benjamin Franklin discovered electricity with his famous kite-flying experiments in 1752. Alessandro Volta‚ an Italian

Conductance and Insulation OVERVIEW: Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are silver‚ gold

to supply electricity to cities in the late 1880s is often called the ’War of Currents ’‚ as this battle ultimately decided which type of current became the standard for the generation of electricity today. Due to different advantages and disadvantages‚ Edison promoted direct current (DC) for electric power distribution‚ whereas Westinghouse and Nikola Tesla both advocated alternating current (AC). Edison ’s direct current was initially the standard for the United States for electricity distribution

Consumption Of Electricity Partial Fulfillment in English IV THE PROBLEM AND ITS BACKGROUND I. Introduction Electricity is a form of energy that is carried through wires. Without electricity‚ we cannot operate things in our home. We use it almost every minute from the time we get up in the morning until we go to bed at night. Electricity helps us in lots of ways. It helps us watch television‚ play computer games and bathe. Without electricity a lot of things we take

The modern age is an age of electricity. People are so used to electric lights‚ radio‚ televisions‚ and telephones that it is hard to imagine what life would be like without them. When there is a power failure‚ people grope about in flickering candlelight. Cars hesitate in the streets because there are no traffic lights to guide them‚ and food spoils in silent refrigerators. Yet‚ people began to understand how electricity works only a little more than two centuries ago. Nature has apparently

Sakib Khan Electric Eels – Physics The animal that is usually known as electric eel is in fact not really an eel but a freshwater species related more to the carp family or catfish family. These unique freshwater predators got their name from the immense electrical charge that they can easily generate to stun or even kill their preys and dissuade predators. Electric eels can grow extremely large which usually can reach as high as 8 foot long and weigh a great amount of 45lbs. In addition to this

Magnetic effect of electric current is one of the major effects of electric current in use‚ without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it‚ which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field
