Why Does Nichrome Have More Resistance Than Copper?

by

Why Does Nichrome Have More Resistance Than Copper? melting point for a nichrome wire is greater than copper wire, so that the resistance at nichrome wire will be greater than copper wire. Which has high resistance Nichrome or copper? Nichrome offers higher resistance than copper. Therefore answer is Nichrome will heat-up faster. Which is better

Do Metals Have Low Resistivity?

Do Metals Have Low Resistivity? Do metals have low resistivity? Metals are good electrical conductors (high conductivity and low resistivity), while non-metals are mostly poor conductors (low conductivity and high resistivity). Why do metals have low resistivity? In general, metals are good conductors. So they offer less resistance to the flow of current. Thus, metals
