Question

a metallic wire has 5 cm length and 50 cm square area of cross section if its resistance is 10 ohm calculate its resistivity at 25 degree Celsius​

Answer 1

Answer:

resistivity = 100

Explanation:

resistance = resistivity * lenght/area

r=rho*l/a

10=rho*5/50

rho=10*50/5

     =100

Answer 2

so here is your answer

it is completely correct
