NZ student accepts $32,000 bid for virginity ..

When I first read the article on internet at Inquirer.net I was not so surprise because actually it is not so shocking to read an article like this because nowadays as pornography and immorality arose to our generation and time many teenagers are now ready to enter this world.As I know pornography is one of the most demanding in the world of business today because of it's online earnings.  But instead of admiring her I felt pity on her because there's so many ways of earning money to pay her university fees.

Introduction of a 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 New Layout

Yes...!!!! I have finally changed my layout. Actually I have been waiting this for so long to changed my layout and finally that day is today...^____^.

Hans Christian Oersted's Discovey

We can conclude from this experiment that an electric current causes a magnetic field around it just like a magnet causes a magnetic field. When you put the compass near the electrical wire with current flowing through it, the compass did not point north; instead, the compass needle pointed in the direction of the current's magnetic field.

Electromanetic Induction

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.
Michael Faraday is generally credited with the discovery of the induction phenomenon in 1831. The materials used to this experiment are magnet, electromagnet and galvanometer.
