Question

the resistance of a wire of length 100 cm and area of cross section 1 mm² is 1ohm .the specific resistance is

Answer 1

Answer:

length= 1m= 100cm

p= 0.01

Explanation:

area= 1 mm²

resistence =1 ohm

R= pl/A

p= RA/L

p=1×1/100

= 0.01 ohms

Answer 2

Answer:

The specific resistance is 0.01 ohms

Explanation:

The resistance of  a wire of length 100 cm

The cross sectional area of the wire 1 $mm^{2}$

Resistance =  1 Ω

R= ρl/A

ρ=RA/L

Specific resistance  ρ=1*1/100

         

                  ρ = 0.01 ohms.
