Electricity and Circuits

Thanks to the hard work of scientists and inventors like Benjamin Franklin and Thomas Edison, we can understand exactly how electricity is created. Electricity is the movement of an electric charge. This electrical charge can be formed by electrons and protons. Electrons have negative charge and protons have positive charge. Electrons can only travel in a loop. If there is an opening of the circuit, electricity will not travel. A light switch is a perfect demonstration of a circuit. When we turn on the light switch, we are closing a circuit. The electrons cannot flow through the circuit, so the lamp is extinguished. The electricity without a given path always seeking the ground. Today scientists are working hard to find safe and renewable ways to generate electricity. For example, solar and wind power are used worldwide to create electricity.

Definition

Employment is defined as any service, function or constant charge and paid, played to keep the employee. It’s a relation exist between employee and employer must be obeyed according to laws.

Exemplification

-    Another example is formal employment, one in which there is bond between employer and employee (unregistered), business is legalized (CNPJ), there is a collection of taxes and benefits, therefore, support the government’s values as FGTS, INSS, Unemployment Insurance and others.

Having completed my studies in 2008. In 2009 I done the first tryout for the Bachelor of Science and Technology (BC&T), Federal University of Rio Grande do Norte (UFRN), which got success.

I'm currently enrolled in BC&T UFRN and MD (Metropolis Digital), technical course program offered by UFRN, I am in third semester. I chose BC&T because i always meant to attend Mechanical Engineering, and how engineering has become a subsequent course of BC&T, decided to do it first and then attend in Mechanical Engineering. And another factor that led me to choose the course of BC&T was the proposal that it brings to create new engineers with a new vision for Science and Technology and Society.
