EXPLAIN 2nd statement
The motion due to random collision.
Which of the following options is correct regarding the given information?
A) I and II are true
B) I and III are true.
C) II and III are true.
D) I ,IIand III are true.
Ans.
I-Drift velocity decreases with increase in temperature. This statement is true.
II-For large current. the drift velocity should be in the order of m/s. This statement is false because drift velocity is in the
of mm/s
Ill-Motion of the free electrons in a conductor is due to the combination of the motion due to applied electric field and the
motion due to random collision. This statement is true.
So. I and Ill are correct.
The correct option is B.
