The bulb will burn for 15 minutes.
Nothing, glass is an insulator.
there will be little or no change
Center terminal is connected to the positive from the battery. Outside is connected to ground (-).
The brightness of three bulb would be mare than one
Both ends of the battery are connected, to make a complete circuit.
The battery connected to the bulb has the potential chemical energy in it when it is connected by means of wire to the bulb the chemical energy in the battery is converted to the electrical energy which flows through the wire to the bulb glows the bulb which is a form of light energy after some time the bulb starts emitting heat which is heat energy.
the bulb will glow and ammeter will show the reading
Chemical Electrical Light
Assuming you're referring to a simple incandescent bulb . . .When the bulb burns out, the filament is open, and it is electrically no longer there.The voltmeter is then across the battery, which is open circuited, i.e. without a load.The meter measures the open-circuit voltage of the battery, nominally 6 V.
Nothing special should happen. What matters for the bulb is the voltage difference between its ends.
a bulb doesn't have a battery it has a curcit connected ( to your house) and a bulb that lights it upadd an ordinary light bulb is much too simple an object as to be able to determine the nature of the source of electrictricity.
