Detailed Solution

The above statement is False.
We know that current can flow when the wire is connected between the two terminals of a battery. Connecting the two terminals ensures that there is a difference in the charge levels due to which current flows. But when both ends of the wire are connected to the same terminal, then there will be no charge difference due to which the current will not flow, and hence the bulb doesn’t glow.
The correct statement would be, an electric bulb glows when the wire is connected between the two different terminals of the cell.
