Question

what will be the resistavity of metal wire of length 2 meter diameter 0.6mm and resistance is 50ohm​

Answer 1

Answer:

Explanation:

R=RHO*LENGTH/AREA

where rho=resistivity

R= resistance

here radius =0.3mm=0.3*10^-3

50=resistivity*2/pi*0.09*10^-6

resistivity=(50*pi*0.09*10^-6)/2

              =7.065*10^-6
