• question_answer Two bulbs X and Y having same voltage rating and of power 40 watt and 60 watt respectively are connected in series across a potential difference of 300 volt, then [Orissa JEE 2005] A)            X will glow brighter B)            Resistance of Y is greater than X C)            Heat produced in Y will be greater than X D)            Voltage drop in X will be greater than Y

Resistance$\propto \frac{1}{\text{power}}$. Thus, 40 W bulb has a high resistance. Because of which there will be more potential drop across 40 W bulb. Thus 40 W bulb will glow brighter.
