Resistance & Cross Section are Inversely Proportional
Explanation:
(a) Nichrome wire of higher length!
- The resistance of a wire depends on its dimensions as well as on the conducting ability of the material from which it is made.
- Short wire has less resistance as compared to long.
(b) Nichrome wire that too thin.
Thick wire has lower resistance.
- It is been said that resistance and cross section of wire are inversely proportional to each other, as electrons flow in larger area. The same does not depend upon thickness of wire.
