Witryna15 paź 2024 · In comparison, distilled water is a very poor conductor of electricity since very little electricity flows through water. Highly ionized substances are strong … 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…

Witryna1 dzień temu · Because stainless steel is a metal alloy, it has the property to conduct electricity but is not as strong as copper or aluminum. Therefore, stainless steel is a poor conductor of electricity. While carbon steel offers a resistivity that is eight times higher than copper, stainless steel has a resistivity that is 40 times higher than copper.
