WHAT IS THE MOTION CHARGES HAPPEN INSIDE THE WIRE WHEN 1).CURENT IS FLOWING AND WHEN 2). CURRENT IS NOT FLOWING?AND ALSO DESCRIBE THE DIRECTION IN WHICH FORCE IS APPLIED ON CHARGE  AND THE DIRECTION OF VELOCITY(OR DISPLACEMENT)OF CHARGE IN BOTH CASES:1).CURENT IS FLOWING AND WHEN 2). CURRENT IS NOT FLOWING?EXPLAIN WITH HELP OF DIAGRAM

Expert Answer:

Current is nothing but the flow/motion of charges/electrons. So, when current is flowing it is due to the electrons moving from the negative terminal of the battery to the positive terminal. It is due to the convention that flow is considered for positive charges and so current is considered to flow from positive to negative and electrons flow from negative to positive.
 
The force applied on the charge comes from the battery itself. The potential difference creates a force in the direction from positive to the negative terminal. Same is the case of velocity.
