Would the bulb glow in the circuit shown in Figure?

उत्तर
The bulb will not glow. This is because the two terminals of the cell are connected to the single terminal of the bulb. This is equivalent to the bulb not being connected to the circuit at all. The two terminals of the battery should be connected to the two terminals of the cell.
