Question

for two wires of same length and different radii does the resistance of wire change give reasons​

Answer 1

Answer:

because resistant is inversely proportional to the area i.e. inversely proportional to the square of radius.

Hence,it will change inversely as the square of the radius.

Answer 2

Answer:

Yes,resistance of the wire changes.

Explanation:

As we know that,

R is proportional to length and also inversely proportional to area.

As area of the wire depends on radio of the wire.

Resistance (R) changes according with the area too.

HOPE U UNDERSTOOD THE PROPORTIONALITY AND INVERSE PROPORTIONALITY IN THE RESISTENCE FORMULA.

HOPE IT IS HELPFUL TO U!
