What is the resistance of 6.2mi of copper wire with a diameter of 0.57mm ?
The answer is suppose to be in Kohm
for the resistance i got 656.9 ohm but don't know how to convert it in to kohm
1000 ohms is a kilo-ohm (kohm)
656.9 ohm would be 0.6569 kohm
I have not checked if your number is correct. You would have had to use a resistivity value for copper.
rho = 16.8*10^-9 ohm-meters is an accepted value at room temperature
