Vedclass · Answer

(B) When bulbs are connected in parallel,the potential difference $(V)$ across each bulb remains the same.The power consumed by a bulb is given by the formula $P = V^2 / R$.Since $V$ is constant,the power consumed is directly proportional to the brightness of the bulb.Bulb $C$ has the highest power rating $(100 \, W)$,followed by bulb $B$ $(60 \, W)$,and bulb $A$ $(40 \, W)$.Therefore,the brightness of bulb $C$ will be the maximum,and the brightness of bulb $A$ will be the minimum.Comparing the options,the brightness of bulb $B$ $(60 \, W)$ is indeed more than that of bulb $A$ $(40 \, W)$.

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?
