Electricity – The Best Conductor of Electricity? – Many types of materials can conduct electricity, but when it comes to the best conductor of electricity, it’s hard to beat copper. In fact, copper is used in all sorts of electrical appliances and equipment because it has so many uses. Copper has been in use since 4000 B.C., and people have been smelting copper since 4000 B.C., which makes it one of the oldest metals known to man and the oldest metal used in modern technology.
In physics, the term conductor refers to materials that allow an electric current to pass through them, easily transmitting the charge from one end of the material to the other. Metals like copper and aluminum are examples of good conductors; electricity flows through them easily because electrons can move freely in these metals and provide the current with little resistance or opposition. Because some materials are better conductors than others, it’s important to understand what makes a good conductor of electricity and how you can maximize your use of electricity by using good conductors when possible.
The answer to this question might surprise you! Contrary to popular belief, steel conducts more electricity than copper. Copper’s main strength is that it provides a very tight grip on electrons, which means it can carry a lot of electric current without getting hot and also allows for wires to be much thinner than those made out of other metals. Steel’s good attributes include its high-heat resistance, which can protect wires from overheating. Plus, steel costs less than copper. That said, there are tradeoffs: steel requires more insulation due to its conductivity. If used improperly, not enough insulation can lead to what’s called flashover, which could lead to an explosion or fire when the electric current travels through air and makes contact with something flammable like oil or natural gas.
The way electrons move through a material affects the speed at which they can travel. It also determines whether or not that material is a good conductor. Platinum, for example, may be too expensive to justify as a metal wire in an electric circuit. However, gold wire has been used for centuries in electrical circuitry because it conducts much faster than copper does. That’s not to say you should disregard copper though—its conducting ability and resistance are ideal for low-voltage applications such as lighting installations and certain radio frequency circuits. Plus, it’s relatively inexpensive and easy to come by.
A problem arises when using metals like iron (commonly found in steel) or aluminum (found in pots and pans). They have poor conductivity so they cannot carry large amounts of current without heating up. A solution for this is to coat the materials with layers of silver, zinc, or brass; this prevents direct contact between the poor conductor and the current.
The earth’s surface is insulated by the atmosphere, meaning that currents can’t flow through it. Air and water are terrible conductors of electricity because air doesn’t have any free electrons, and water contains so many dissolved ions that current can’t move quickly through it. Saltwater doesn’t have as many ions as freshwater, but salt water has charged particles (mainly ions) in it. Saltwater contains chloride ions that conduct charges well but diffuse quickly–at a rate up to 200 times faster than an ion from freshwater or sea water. Because of this, it’s possible for a person standing on the shoreline to be hit with a sudden shock when touched by seawater.
A graphite powder has a lot more free electrons, but is not stable at room temperature. Silicon nitride and silicone are semiconductors which are also great because they do not react with water or most chemicals. Silicon nitride is great for cooking pans. Another well-known semiconductor material used in electronics, silicone rubber, can also be considered as a solid choice. It does not interact with air or water and can withstand high temperatures (up to 300°C). But silicone needs to be sealed in an inert gas like nitrogen or argon to avoid reactions with other elements.
One of the most important properties in a material to take into account when looking for a good conductor of silver wire or any other conductor, is that it should not be magnetic. The way this comes into play with things like electrical wire is that if your wire became magnetized (which it will at some point, depending on its composition) then it would pull on and break the electrons apart from each other as they raced through. One other thing to keep in mind when using materials like copper or silver, while they are both highly effective conductors, copper is more costly and therefore more expensive to use in most electrical situations. For all these reasons, copper tends to be better suited for larger-scale jobs where money isn’t as much an issue.
One of the strongest metals in its category, magnesium has many strengths and thus is used in a variety of ways. Magnesium is a less expensive metal, making it an economical choice for those looking to save money on their projects. It also has low corrosion rates. This can be seen by corrosion testing done to magnesium that lasts well over 10 years with negligible effects compared to other metals like aluminum and steel. Finally, magnesium’s high-temperature resistance makes it perfect for high-voltage applications such as electric furnaces or transmission lines. However, it’s important to note that magnesium ribbon is quite fragile so care should be taken when handling this material.
The best conductor of electricity would be metal because it conducts with both the efficiency and ease. For example, in metals, electrons are shared by all atoms and are always on the move. This makes metal a good choice for electrons to travel quickly and easily without energy loss. Metals can also act as a shield to keep electrons from bouncing around within the material, which decreases its conductivity. Copper has an electrical conductivity of 100% per cent; aluminum at 95%; silver at 86%.
