Explain why the bulb would not glow in the arrangement shown in the figure.


In the given arrangement, shown in the figure, the bulb would not glow because one end of the of the screw driver is made up of metal and the other end is made up of plastic which does not allow the electric current to flow through it. Thus, the circuit is disconnected due to presence of an insulator in between. Hence, bulb will not glow.
