Question

if the resistance of a certain copper wire is 1 ohm then the resistance of similar nicrome wire will be about ​

Answer 1

Answer: Then, l/a=R/ρ = 1/(1.68E-8) / meter. =77.381 ohms. Therefore, the required resistance of Nichrome wire is 77.381 ohms.

Answer 2

Answer:

Then, l/a=R/ρ = 1/(1.68E-8) / meter. =77.381 ohms. Therefore, the required resistance of Nichrome wire is 77.381 ohms.
