Electrical conductivity plays a vital role in understanding the flow of current and the transmission of electricity. It is a parameter that relies on charged particles known as ions, determining the level of current transmission. This article delves into the concept of electrical conductivity, exploring why metals have exceptional conductivity and the factors that influence it. It also highlights the top 10 metals with the best electrical conductivity. Come along on this enlightening journey to uncover the secrets behind the conductivity of metals and their significant role in electrical devices.
What is electrical conductivity?
Electrical conductivity is a parameter that indicates the level of current transmission or electrical conductivity of a substance. This parameter depends on charged particles known as ions, which include negative ions (-) or positive ions (+).
According to Ohm's law on electrical conductivity, current is directly proportional to the corresponding electric field, and the conductivity parameter is represented by the following formula: "Current density = Electric field strength x conductivity".
Electrical conductivity is inversely related to resistivity, and both values are scalar quantities. The unit of electrical conductivity is measured in millisiemens per centimeter (mS/cm), while in the US it is measured in terms of % IACS. For high voltage lines, the conductivity of overhead wires is measured in % IACS.
Why can metals conduct electricity?
Before exploring the best conductive metals, let's first understand why they have the ability to conduct electricity! As you may know, the atoms inside metals form a matrix through which electrons on the outside can move freely.
Instead of orbiting their corresponding atoms, electrons will orbit around the positive nuclei of metal ions. They will then move freely, allowing metals to have good electrical conductivity.
Factors affecting the electrical conductivity of metals
Metals have excellent electrical conductivity, which is why they are used extensively in the production of electrical devices. But why do metals have such good conductivity? Let's find the answer to this question.
Good conductivity is one of the most prominent characteristics of metal groups due to their specific structure. The structure of metals consists of many negatively charged electron particles that move freely and can easily move through compounds and other objects.
Why do metals have the best conductivity?
When an electric voltage or external force is applied, the electron particles will move more strongly, forming an electron sea surrounding positively charged particles that continue to move and create electric currents. This is what makes metals conduct heat the best. Although each metal has different electrical conductivity, in general, they have a more prominent ability to conduct electricity compared to non-metals or other compounds.
