Assignment 2 unit 3 Describe methods of producing A.C. and D.C electricity. There are two type of electric current it is known as direct current (DC). The other one is known as alternating current (AC). However‚ an electric current can be produce by moving a magnet inside a coil‚ wire‚ so the size of this induces current and it is able to increase by moving the magnet faster. This is using a stronger magnet‚ so increasing the number of the turns‚ coils. It may be able to increase its area but the

Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

.INTRODUCTION Magnetic levitation is the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard‚ an American Rocket scientist‚ created a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years‚ but it was not until the 1970’s that Japan and Germany showed interest in

CHAPTER 1 INTRODUCTION 1.1 Background of the study Today energy is so expensive‚ since the populace on the entire world improves and we consume energy in dozen of forms. Yet all of the energy we use originates in the power of the atom including our sun. The energy we capture for use on earth comes largely from the sun liked solar and other such as geothermal‚ wind turbine‚ biomass_______ . Energy Consumption is a key part of most human activities this consumption involves converting one energy

Permanent Magnet Moving Coil: Principle of Working When a current carrying conductor is placed in a magnetic field‚ it experiences a force and tends to move in the direction as per Fleming’s left hand rule. Fleming left hand rule: If the first and the second finger and the thumb of the left hand are held so that they are at right angle to each other‚ then the thumb shows the direction of the force on the conductor‚ the first finger points towards the direction of the magnetic field and the second

Electricity Project Electricity is a form of energy involving the flow of electrons. 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. They even made cars that run off electricity. So‚ electricity is no longer a strange thing. Electricity is a basic

Induction Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction. This is called induction because there is no physical connection between the conductor and the magnet. The current is said to be induced in the conductor by the magnetic

"Electrical Energy Consumption" Sustainability and electricity Where does electricity come from? Most people use electricity and see it as something that is infinite and probably don’t give a second thought about its source. This is quite understandable‚ considering electricity looks clean; it doesn’t cause any noise pollution or direct air pollution. The fact is that most electricity is produced by burning coal‚ and the use of nuclear power plants. Simply stated‚ the more electricity used‚
