Question

A wire of length 1 and resistance R has area of
cross-section A. What will be the length of the wire
of same material and same resistance R having area of cross-section A/3​

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
