It is also easy to transform it into direct current. The main advantage of alternating current is that, when transmitted over long distances, less energy is lost than with direct current. It also has the advantage that it can be stored in batteries.
It requires less insulation and lower voltages can be used. The main advantage of direct current is that it tends to be safer than alternating current. This is the current that travels through the power lines to the sockets in our homes. Alternating current: this flows cyclically, fluctuating in magnitude and direction at regular intervals.Direct current: does not vary in time, since the flow is stable and unidirectional.These electrons flow differently in direct current and alternating current: This means that they can leave, going from one point to another and generating electric current as they do.Īll electric current is a flow of electrons that travels from a positive pole to a negative pole.
Without going into too much technical detail, suffice to say that matter is formed by atoms and that their outer layers contain electrons that are only loosely attached to the nucleus of the atom. But before the battle began, which the newspapers of the time called "The War of the Currents", some context is required. One of these battlefields was electricity, where two very different visions clashed: Nikola Tesla, the proponent of alternating current (AC) and Thomas Alba Edison who advocated direct current (DC). It was an exciting period, full of scientific advances, during which the vigorous development of capitalism caused struggles and confrontations between different ideas and patents. I am proud of the fact that I have never invented weapons to kill….The nineteenth century was the time of the great inventors. I want to save and advance human life, not destroy it…. “My main purpose in life is to make enough money to create ever more inventions….
“When I have finally decided that a result is worth getting, I go ahead on it and make trial after trial until it comes.” “A genius is often merely a talented person who has done all of his or her homework.” Its sale is proof of utility, and utility is success.” “Anything that won’t sell, I don’t want to invent. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence and honest purpose, as well as perspiration.” “Being busy does not always mean real work. Besides the short catnaps I take each day, I average about four to five hours of sleep per night." “Personally, I enjoy working about 18 hours a day.
