Materials with low resistivity are good conductors of electricity, while materials with high resistivity are poor conductors.<\/p>\n<p>Copper has the lowest resistivity of any common metal. It is also a very ductile and malleable metal, which makes it easy to work with. These properties make copper ideal for use in electrical wiring and other applications where good conductivity is important.<\/p>\n<p>Zinc, lead, and mercury are all metals with higher resistivity than copper. They are not as good conductors of electricity, but they do have other properties that make them useful in certain applications. For example, zinc is used to coat steel to prevent corrosion, lead is used in batteries, and mercury is used in thermometers.<\/p>\n<p>In conclusion, copper has the least resistivity of any common metal. It is a good conductor of electricity and is also ductile and malleable, which makes it ideal for use in electrical wiring and other applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Zinc&#8221;
