VITEEE
VITEEE 2008
A
the collisions of the conducting electrons with the electrons increase
B
the collisions of the conducting electrons with the lattice consisting of the ions of the metal increase
C
the number of conduction electrons decreases
D
the number of conduction electrons increases
Solution:
The resistance of a metal increases with increasing temperature this is because, with increase in temperature the ions of the conductor vibrate with greater amplitude and the collision between ions and electrons becomes
