Electrical Device Between Two Circuit Through...

INTRODUCTION The transformer is an electrical device which transfers energy between two circuit through electromagnetic induction. Transformer may be used as a safe and efficient voltage changer to change the Alternating Current voltage at it’s input to a higher and lower voltage at its output without changing it’s frequency. Other uses include current conversion, isolation with or without changing impedance and voltage conversion. A transformer consists of two windings of wire that are wound around a common core and it provides tight electromagnetic coupling between the windings and makes a couple. The core material is may be of a laminated iron core. The coil that receives the electrical input energy is referred to as primary winding, the output coil is secondary winding. An alternating current flows through the primary winding coil of a transformer generates electromagnetic field which varies in its surroundings and induces a varying magnetic flux in the core of a transformer. The electromagnetic field varies in the vicinity of the secondary winding induces an electromotive force in a secondary winding and appears as a voltage across the output terminals. If a load is connected across the secondary winding, a current flows through the secondary winding and drawing power from the primary winding and its power source. A transformer cannot operate with direct current(DC). When connected to a Direct Current source, a transformer typically produces a very short outputShow MoreRelatedApplications Of Faraday s Law Of Electromagnetic Induction1933 Words   |  8 PagesLaw of Electromagnetic Induction Prepared by: Ravi Ramlogan ID# 61928 Date Submitted – 01/10/16 Summary: This report looks into electromagnetic induction as an incredibly useful phenomenon with a wide variety of applications. We explore faraday’s laws of induction applications and construction on how the laws applies to equipment and processes around us. The law has far reaching consequences that have greatly impacted mankind after its discovery. Faraday’s discovery of electromagnetic inductionRead MoreEssay Electromagnetic Induction1369 Words   |  6 PagesFaraday was a chemist and physicist from England. He invented electromagnetic induction in 1831. Electromagnetic induction as defined by Stuart Bushong is: An electric current is induced in a circuit if some part of that circuit is in a changing magnetic field. This observation is summarized in what is called Faraday’s Law, or the first law of electromagnetics. After a series of different experiments, Faraday determined that an electrical current cannot exist just by the presence of a magnetic fieldRead Mo reA Brief Report On Energy Conversion977 Words   |  4 Pagesread book of scientific subjects while he worked as a book binder. In 18th century Faraday discovered electromagnetic induction, the principle behind numerous medical, industrial, technological and other applications. Faraday’s law explains the relation between a time varying magnetic field and an induced electric field. Electric Generator Generators transform mechanical energy to electrical energy. The AC generator consists of a loop of wire mostly rectangular which is rotated by some externalRead MoreDesign A Simple Electric Motor1359 Words   |  6 Pagesdesign a simple electric motor and understand its working, we need to have knowledge about the following, ïÆ'Ëœ Electric field and Magnetic field ïÆ'Ëœ Faraday’s Law of Electromagnetic Induction ïÆ'Ëœ Fleming’s Left hand Thumb rule ïÆ'Ëœ Lorentz Force ïÆ'Ëœ Torque ELECTRIC FIELD: The electric field is a vector.

Explain the details behind wind power Wind energy is generated by changing wind currents into alternative types of energy using wind turbines. Winds are generated by complicated mechanisms involving the rotation of the temperature gradients between land and ocean, therefore the physical effect of mountains and alternative obstacles. How is wind turbine designed? Wind turbines are machines that convert the winds kinetic energy into rotary energy, that is then accustomed work.

In this case, a laptop or cell phone can charge itself easily and seamlessly just by being placing inside a room. This is the ability of many experimental wireless power devices that will be adapted to domestic use in the future. Today, the prevailing methods of energy transfer are wires and batteries. Wired connections are perhaps the most common. With this energy transfer method, energy is delivered from a power plantRead MoreOne application of magnetic fields in household appliances.3425 Words   |  14 Pagesdeveloped when this force is applied at a given distance from the axis of the rotor. Most electromagnetic motors are rotary, but linear types also exist. In a rotary motor, the rotating part (usually on the inside) is called the rotor, and the stationary part is called the stator. The motor contains electromagnets that are wound on a frame. Though this frame is often called the armature. The electromagnetic field works as shown in the diagrams below. DC motors.

During this period of time the foundations of modern electrically based technologies were discovered. The nineteenth century began with a debate between Luigi Galvani, and Alessandro Volta regarding the source of electricity in Galvani’s famous frog experiment. These debates lead to the invention of the battery by Volta, and the inventionRead MoreInvestigating How Different Components Of A Motor Affects Its Performance Capabilities1717 Words   |  7 Pagestransform electrical energy into mechanical energy (Interne t 1).
