    OK.

    Materials specs

    battery 12 volts 12 ah (as usual :D)
    fuse (12 volt/1 ampere (let's say))
    bulb (12 volt/5w :D :D)

    Ok, the line 1 joined the terminal - and + causes it to short-circuit. but it's have own fuse to protect itself. :D so, it will not affect the line 2?

    as you may notice, both line have their own connection. they are directly put on the battery.

    um,what's your comment? am i correct? i hope so.;)

    It takes time (maybe 1 second or two seconds because the battery is not very powerful) for the fuse to heat up then burn out. During this time the the battery is shorted by line 1 and the light bulb will be very dim.

    But after one or two seconds, the light brightness will back to normal?

    I guessed one or two seconds because I don't know your battery and I don't know your fuse. The fuse might burn out in 10 seconds.
    When the fuse burns out then the battery returns to normal with only a small anount of its charge gone.
