Bulb glows when the bulb is connected to positive and negative terminals of battery or source.
The circuit must be closed.
The circuit must be complete for the bulb to light, otherwise no current will flow. A current will flow for a very short period of time, but then a concentration of charge will form that will create a potential difference negating that potential difference from the batteries.
