Who are people or events that influenced you most throughout your life?

My Parents, Relatives, Childhood friends and all of my classmates are the people who influenced me most throughout my life. And all of the events specially the events of happiness like in bonding with the people who are important to me and who give me strength to live in this world. They influenced me a lot for being a good person and how to be a person that complete the world as a our land. Also all of my teachers or what we call our second parents influenced me throughout my life for such a good reason that they mold and help me on how to improved myself and to be able to achieve my goals in life. Trough of all your guidance, you make me as a better person in a sense that you teach everything, doing good things and in improving my life. Deeply, I will always treasure it more that a precious stone. To sum it up, all of you who influenced my life will not be erase in my mind and in my heart because you've never let me down instead you raise me up just like a rising sun and in getting me out of my shell to show how wonderful the world is.

Principles of Transformer

•Difference between Step-up and Step-down Transformer.

     Step-up Transformer- if the number of loops in the secondary coil is greater than that in the primary coil so that the induced voltage is greater than the input voltage.

     Step-down Transformer- a transformer that has less loops in the secondary than that in the primary, the induced voltage in the secondary coil is less than that in the primary coil.

•Appliances or Equipment that requires transformers.

       The appliances or equipment that requires transformers are Television, Sound system, Refrigerator, and etc., which  needs a voltage except 220 V source.

•Relation of the voltage and current in the primary and secondary coils to the number of turn in each.

       If the number of coils in the primary coil is lesser,  its voltage and current is also lesser and if it have many loops its voltage and current is greater because the more the number of coil the more the current and voltage flows and has a greater supply. And the same as in the secondary coil.

   

      

    

    

     

My Reaction about the article "NZ student accepts $32,000 bid for virginity"

Actually, this article is so surprising in the sense that, a particular student bidding her own virginity that can cause her in danger like having an HIV disease and any transmitted disease. As you read it, she give her own virginity to have a money that could help her for paying her tuition fees. And I think it is very common problem in our generation which is the financial aspects because of lacking in money. And in order to have a good education that could make you better in the future you will do anything to have it. Just like what happen in the student in New Zealand. And don't think if it is the best solution because for me its just like selling your spirits in a devil. Besides, you can take another solution for that particular problem that could not put you at risks.

Electromagnetic Induction

Hans Christian Ørsted

Hans Christian Ørsted was a Danish physicist and chemist who is most widely known for observing that electric currents induce magnetic fields, an important aspect of electromagnetism. He shaped post-Kantian philosophy and advances in science throughout the late 19th century.

•Faraday and Henry performed lots of experiments to learn about the connection between electricity and magnetism. The results of these experiments have led to the life styles of today's men, who made life easy by using lots of electrical applications.
The research that established Faraday as the foremost experimental scientist of his day was, however, in the fields of electricity and magnetism. In 1821 he plotted the magnetic field around a conductor carrying an electric current; the existence of the magnetic field had first been observed by the Danish physicist Hans Christian Oersted in 1819. In 1831 Faraday followed this accomplishment with the discovery of electromagnetic induction and in the same year demonstrated the induction of one electric current by another.

•Electromagnetic induction- is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field.

•They use electromagnet, magnet and galvanometer in their experiment.
