Question

with original value,
07.Calculate the resistivity of wire having length Im and area of cross section 121 X10-6 m2. If its
resistance is 0.014 ohm,
Section 3x10-4 m2​

Answer 1

Answer:

I = 1.0 m

R = 23 ohm

p = 1.84 × 10-6 ohm – meter

We have

R = P. I/A

23 = 1.84 × 10-6 × 1/A

A = (1.84 × 10-6 )/23

= 0.08 × 10-6 m2

= 8 × 10-8 m2
