What happens if the cross-section of the conductor is made thinner?

1.	What happens if the cross-section of the conductor is made thinner?
Answer» The resistance of the wire will increase if we made the conductor thinner because\xa0R (resistance) = p (rho). l (length) / A (area of cross-section or thickness of wire).Area is directly proportional to the radius of the wire.So as you can see if area of cross-section ( or thickness) of wire increases, resistance decreases and more current flows through it.\xa0
