Two bulbs of 100w and 40w respectively connected in series across a 230v supply which bulb will glow bright and why?

Two bulbs of 100w and 40w respectively connected in series across a 230v supply which bulb will glow bright and why?
Answer : In this case, the two bulbs (100W and 40W) are connected in series across a 230V supply. To understand which bulb will glow brighter, we need to look at the power consumed by each bulb. ... voltage drop and thus dissipate more power, even if it is designed for lower power under normal conditions....
