Question

9th If the resistance of wire A is four times the resistance of wire B and the ratio of their cross sectional areas​

Answer 1

Answer:

The ratio of the cross sectional area and radius are 1:2 and 1:√2. So, The resistance of the wire is inversely proportional to the square of area of cross section. Hence, The ratio of the cross sectional area and radius are 1:2 and 1:√2.
