In an electrical circuit, three incandescent bulbs A, B and C of rating 40 W; 60 W and 100 W respectively, are connected in parallel to an electric source. Write the order of brightness.
Bulbs are rated presuming that they all are to be connected with the same voltage supply (say 220 V in India). In parallel combination, voltage remains same, so greater the power (watt), greater the brightness. Therefore, brightness B of three bulbs are as
