Unit 4 Assignment 1 Copper vs. Fiber Paper Copper wire is found in most household electric or electrical related devices. One advantage of copper wire is its conductivity. Copper wire is second only to silver wire in level of conductivity meaning it will accept a current more so than almost any other type of wire. Copper wire is also heat resistant and can handle high levels of charge without many issues with overloading the wire. Copper in itself is also resistant to corrosion. This helps
