The Effect Of Electricity On The Human Body

1708 Words7 Pages
. Review of Literature Electricity is seemingly inescapable and is used in many aspects of everyday life, such as heating, lighting, refrigeration, entertainment, and many other uses. Electricity increases human efficiency by lighting homes and sidewalks even after the natural light of the sun has gone away. Despite all the uses of electricity, many do not know what electricity actually is. Electricity is defined as a flow of charged particles. This flow occurs when atoms fall out of balance and electrons are transferred between ions [charged particles], in order to balance them (California Energy Commision, 2012). This context of must be used to understand the relationship between electricity and water and the way that this relationship…show more content…
This means that chemicals cause an electrical signal” (Chudler, 2015). The nervous system contains four main ions which include sodium (Na+), potassium (K+), calcium (Ca2+), and chloride (Cl-). It is also important to note that the neurons are enclosed by a semipermeable membrane, meaning that only certain ions can get through. Furthermore, researchers at Macalester College state, “the cell has a resting potential of -70 mV, meaning that the intracellular space is more negative relative to the extracellular space” (Gilmore, et al., n.d). Thus, the cell, due to its potential and the chemicals which it contains, permits an electrical current similar to a battery. According to the Massachusetts Institute of Technology’s (MIT) School of Engineering, a battery consists primarily of “two terminals made of different chemicals (typically metals), the anode [negative terminal] and the cathode [positive terminal]; and the electrolyte, which separates these terminals” (MIT, 2012). The electrolyte is a chemical medium which regulates the flow of electrons between the positive and negative terminals. Due to the fact that the
