he density of free electrons in gold is 5.90x10^28 m^-3. The resistivity of gold is 2.44x10^-8 ohms.m at a temperature of 20 C and the temperature coefficient of resistivity is 0.004. a gold wire 1.1 mm in diameter and 26 cm long, carries a current of 760 ma. what is the drift velocity of the electrons in the wire?
