Question

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. Which of the following is likely to happen regarding their brightness ?
A. Brightness of all the bulbs will be the same
B. Brightness of bulb A will be the maximum
C. Brightness of bulb B will be more than that of A
D. Brightness of bulb C will be less than that of B

Answer 1

Correct Answer - C
In an electrical circuit, three incandescent bulbs A, B and C of rating 40 W, 60 W and 100 W are connected in parallel to an electric source, then the bulb w9th the highest wattage glows with maximum brightness. Power dissipated `prop` Brightness. Thus, the this brightness different bulks are in following order
`B_(100) gt B_(60) gt B_(40)`.
