Current will not flow through the 4 V cell that is connected across A and B ,
because this 4 V cell is not a part of any closed circuit.
 
A cell will deliver current only if it is a part of closed circuit. In the given figure , 4 V cell is isolated .
 
Currents in the left side and right side circuit are shown above

  Earthing provides a safety measure for electrical circuits and appliances. A thick metal plate is buried deep into the earth and thick wires are drawn from this plate; these are used in buildings for the purpose of earthing near the mains supply. Why only "thick" wire and "thick" metal plates are used?

Sir the ans to this quesn is i3=-5/6 A so this means curretn flows from A to D (opp to current indicated in diagram) but through KVL we found PE at D is always greater than A, C,E hence it will always flow from D to other points. 1) How it is voilating Ienter=Iexit. 2)How current flows from A to D even though D is high PE?
