The resistance of a given conductor depends on the material it is made of, and on its dimensions. For a given material, the resistance is inversely proportional to the cross-sectional area. For example, a thick copper wire has lower resistance than an otherwise-identical thin copper wire. Also, for a given material, the resistance is proportional to the length; for example, a long copp… WitrynaWhen there is too much current, it can cause electrical shock, burns, and even death. By increasing the resistance of electrical equipment, the amount of current flowing through it can be limited, making it safer to use. The Drawbacks of Electrical Resistance kshaw willisisd.org
