    Four bulbs \[{{B}_{1}},\]\[{{B}_{2}},\]\[{{B}_{3}}\]and \[{{B}_{4}}\] of 100 W each are connected to 220 V main as shown in the figure. The reading in an ideal ammeter will be:

    A) 0.45 A              

    B) 0.90 A

    C) 1.35 A  

    D)        1.80 A

    Correct Answer: C

    Solution :

    [c] Current in each bulb \[\text{=}\frac{\text{Power}}{\text{Voltage}}\] \[=\frac{100}{220}=0.45\,A\] Current through ammeter \[=0.45\times 3=1.35\,A\]
