Question

A given resistance wire has A resistance of 6.0ohm . How will it's resistance change if
a)only it's cross section area is doubled and
b) only the radius of the wire is doubled.

Correct answer will be given brainliest and up to 100 ponts​

Answer 1

Answer:

Doubling the length of your wire should double its resistance. Doubling its cross section area will halve its resistance. Doubling its radius will quadruple its cross sectional area (A=πr², where A is cross sectional area and r is radius)
