Two bulbs of power P1 and P2 are connected in the circuit.Now P1 is greater than P2.Then,which bulb glows more brightly and why?

Hi Ayan,


Given that we do not have a clarity on the nature of the connection of the circuit i.e series or parallel we have analyzed the most practical solution for you!

Power of a bulb is actually a consumable power required by the bulb to perform at its best-rated condition.

So a bulb with higher power rating will glow more (in comparison with the bulb of low power) if the current supply meets the functioning requirement.

Whereas, if the current supply is lower than the required rating for the bulb with higher power then the bulb with low power will glow more.
