    Hello,

    my two bulbs is rated as 12 v 5 w. so means that both wire (line 1 and line 2) is pulling 0.4166667 seperately. (i mean line 1 is pulling 0.4166667 amps at the same line 2 is also pulling 0.4166667 amps.).

    But the main wire (where line 1 and line 2 were connected), how many amps were being pulled there? :D

    is it not 0.8333334. (twice)?

    if it is correct, means that if ten lines were connected there. and those lines is pulling 0.4166667. means that the main line were pulling 4.166667?

    pls, answer me. thanks.

    see my schematic below.

    In a parallel ckt. the total current is the sum of the individual currents; so yes, .416 A.

    Yep, just be careful with paralleling things other than light bulbs, sometimes they won't share nicely, and things get ruined.
