  1. current in circuit=12/(1+2+3)=2a
    potential across each bulb= I^2 R = 4R

  2. 6Ω total resistance , so 2A current

    potential difference = current * resistance

  3. I = E/Rt = 12/(1+2+3) = 2A.
    V1 = I * R1 = 2 * 1 = 2 Volts.
    V2 = I * R2 = 2 * 2 = 4 Volts.
    V3 = I * R3 = 2 * 3 = 6 Volts.
