    The short method of finding power of second bulb if power and voltage of first bulb is given:
    You can use unitary method, if you use unitary method, multiply your answer by multiple of the potential of first bulb { V1 } given in question.
    For example,
    a bulb is given of 220 V and 100 W and second bulb is given of 110 V, then find power in second bulb....
    Answer: 220V -> 100W
    110V -> x
    x = 110V * 100W / 220V
    x = 50
    110 is 1/2 multiple of 220 i.e, V2 = 1/2 V1
    therefore, now multiply the multiple of V1 with x
    P = x * 1/2
    P = 50 * 1/2
    P = 25W
    keep units in SI units only

    bulbs in parallel have equal voltage so III > (I,II)
    but in series bulb with lower power hase more brightness so II > I
    Hence III > II > I :)
