Boojho has a cell and a single piece of connecting wire. Without cutting the wire in two, will he be able to make the bulb glow? Explain with the help of a circuit diagram.

Our problem here is that,

we have to connect the bulb using only one wire. The way to do so is to connect one terminal of the bulb directly to the negative terminal of the electric cell by doing so we will no longer require any other wire for our electric circuit.

In the picture as you have observed the negative terminal of the cell is directly connected to the bulb without any wire.
