    Thanks for using Brainmass.

    Solution:
    1. A. Since both bulbs are identical, the voltage drops across the 2 bulbs are equal. So the two will receive half of the supply voltage. So the answer is:
    Vbulb = 1.5V

    B. Using voltage divider formula, we can get the voltage across the 2-ohm resistor:
    V_2*omega = 3V((2*omega)/(2*omega + ...
