A) Drift velocity alone
B) Thermal velocity alone
C) Both drift velocity and thermal velocity
D) Neither drift nor thermal velocity.
Correct Answer: A
Solution :

| And, current (I) also depend on n, the number of free electrons which increases on increasing temperature which makes more collision between electrons and increases resistance or decrease current. |
