It's not widely realised that incandescent lamps have a fuse element in series with the lamp base and the filament. This fuse is designed to prevent the lamp exploding in the event of a failure of the filament which results in it being short circuited.

What happens to bulb when 13 A fuse is connected to 3 A bulb?

What happens? The bulb lights up when power is applied. Fuses protect the wiring and sockets from excessive current flow. If the wires and socket can handle 13 amps without overheating, then all's good. So, replacing the bulb with a smaller wattage is ok; replacing the fuse with a larger capacity fuse is bad.
