Choose the correct option with respect to the statements A and B (A):When no electric field is applied across a conductor, the path of free electrons between two successive collisions in it is straight (B): When an electric field is applied across a conductor, the drift velocity of electrons is independent of time

Options

  1. AA and B are true
  2. BA is true and B is false
  3. CA is false and B is true
  4. DA and B are false

Correct answer

A. A and B are true

Step-by-step solution

- (A): In absence of electric field, electrons move freely between collisions ( ) path is straight. ( ) True - (B): In presence of electric field, electrons acquire a constant average drift velocity ( (v_d= e E m )), which does not change with time. ( ) True Hence, both A and B are true.
