Question

I How do you verify that resistance of a conductor i
inversely propostional to the area of cross section of the
Conductor for constant longih and temperature?​

Answer 1

Answer:

Collect iron spokes of different lengths ; with same cross sectional areas. Make a circuit leaving gas between P and Q with a battery, ammeter and plug key. ... From this, we conclude that the resistance of a conductor is directly proportional to its length (l) for constant cross-sectional area. Therefore, R∝L.
