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

Options

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`

Answer

A

Explanation

(a) Resistance `prop (1)/(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.
