In the daily life, you will often find the electrical circuit, the electrical circuit ranging from the simple to the very complex circuit.<\/span> Have you observed the electrical circuits in a flashlight, radio, or television?<\/span> Have you ever wondered why a flashlight, radio, and television can function?<\/span><\/p>\n Examine the electrical substation image below.<\/span> Large cables connect one place to another place with high voltage.<\/span> How does an electrician to string cables so as not to jeopardize it?<\/span> And how electricity can get to your home?<\/span> To find out follow the following descriptions:<\/span><\/p>\n a.<\/strong><\/span> Direction of the flow of electrons<\/strong><\/span> Electron current flows from a negative pole voltage generator through a load to the anode.<\/strong><\/span><\/p>\n b.<\/strong><\/span> The current direction in engineering<\/strong><\/span> Although at this time the assumption has been proved that there were errors in the beginning, but in the electrical engineering for the practical assumption that the current direction is maintained.<\/span> So it was found that the difference between the direction of the flow of electrons towards the current direction in technique or in general also called the current direction.<\/span><\/p>\n

\n We created an electrical current circuit is closed, thus obtained a process as follows: On the negative pole voltage generator (excess electrons), the free electrons in a conductor pushed towards the end of the load.<\/span> At the anode (shortage of electrons) of free electrons on the other end of the conductor of interest.<\/span> Thus in general occurs with a certain direction of electron flow.<\/span>

\n Knowledge of the theory of electron ancient suspect that as the responsible for the delivery mechanism in metals is a positive charge carrier and therefore the current flows from the anode through the load to the negative pole.<\/span> So contrary to the actual flow of electrons as stated upfront.<\/span><\/p>\n
