Question What is the resistance of a 6.0 m long gold wire (ρgold = 5.6 x 10 -8 Ω-m) whose cross-sectional area is 5×10 -7m 2 ? (Please show some work)

Answer: R =0.672 ohms Explanation: We have, Length of a gold wire is 6 m Resistivity of gold is Area of cross section of the wire is The resistance of a wire is given by the relation as follows : So, the resistance of the gold wire is 0.672 ohms. Log in to Reply

Answer:R =0.672 ohms

Explanation:We have,

Length of a gold wire is 6 m

Resistivity of gold is

Area of cross section of the wire is

The resistance of a wire is given by the relation as follows :

So, the resistance of the gold wire is 0.672 ohms.
