Vedclass · Answer

(A) In a parallel circuit,the voltage $V$ across each bulb is the same.The power consumed by a bulb is given by the formula $P = \frac{V^2}{R}$.Since the rated power $P_{rated} = \frac{V_{rated}^2}{R}$,the resistance $R$ of a bulb is inversely proportional to its rated power $(R \propto \frac{1}{P_{rated}})$.Substituting this into the power consumption formula,we get $P_{consumed} = \frac{V^2}{R} \propto P_{rated}$.Therefore,the bulb with the highest rated power will consume the most power and glow the brightest.Thus,the $200\,W$ bulb will glow more.

If three bulbs $60\,W$,$100\,W$ and $200\,W$ are connected in parallel,then
