Question

From the following which one has more conductivity? * 1 point Iron Zinc Copper Aluminium​

Answer 1

Explanation:

Brass is only 28% as conductive as copper. Some bronzes are as low as 7% as conductive as copper! Copper is the standard by which electrical materials are rated and conductivity ratings are expressed as a relative measurement to copper.

Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance. Other elements with high electrical conductivity, are aluminum, zinc, nickel, iron, and platinum.

hope you got the best answer

Answer 2

Answer:

Uses of Aluminium, Copper, Zinc and Iron

Did you know that we describe periods of history according to the metal that was in use during the said period? The Stone age was followed by the Bronze Age and the Iron Age. All modern developments can be traced back to our discovery and effective use of metals. Let us learn about the uses of very important metals such as aluminium, Iron, Copper etc.
