Question

Fig. 3.8 (a): Random motion of 'free' electrons in a
metal wire when a cell or a battery is not connected
(Positive metal ions are not shown in the figure.)​

Answer 1

Answer:

When the ends of the metal wire are not connected to a battery, no electric field is produced inside the wire. Thus no force acts on the electrons in the wire. So the electrons collide with each other and move in random directions.
