Humans and electricity have worked in tandem for years upon years. Electricity plays possibly the largest role of all in today's society. Almost all inanimate objects nowadays require electricity to work. Electricity flows everywhere, like the salty water of the ocean washing up on a hot beach, as euphoria sweeps through you like a breeze whistling through your hair. When it isn't being used in computers, or flowing through your hands it is being used in the human nervous system to give you feeling. Essentially, electricity is life itself.
According to google, electricity is, "a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current." You can find these "charged particles" inside of atoms.
Discovery and Uses
Electricity was used long before the industrial revolution, and in fact, was even used by the ancient Greeks, Romans, and Persians; however it was not used to a further, more useful extent until 1831 when Michael Faraday, a british eclectromagnetic scientist discovered that an electric current was induced in a coil of wire when a magnet, placed near the coil, was moved. However, an argument could be made that the further extent of electricty began in 1819 when Hans Christian Orsted discovered that electricity produces a magnetic field. These discoveries laid the foundation for further uses of electricity such as the lightbulb, the electric motor, and other elaborate contraptions of the sort.
What Are the Positive/Negative Effects of Electricity
The basic answer to this question is that there are no negative effects of electricity, and the positive effects are countless. The long answer; the negative effects of electricy do not lie in the electricity itself, but rather the means of attaining it. There have been countless debates about renewable resources vs. non-renewable resources. For decades and decades coal has been the primary way to attain electricity. However, the problem with coal is that not only is it a non-renewable resource, but it is also terrible for the environment. In the last decade or two we've seen an increase in more natural renewable.
Electricity itself has never changed as far as we know but our uses of it have escalated a lot. Rather than using electric motors; we're using completely elictrically charged cars. As our understanding of electricity increased we have furthered our uses for it. Essentially electricity is life, so as we further our understanding as electricity...we further our understanding of life.
