    High School Which Bulb is Brighter in a Series Circuit: 100W or 40W?

    Thanks a lot. Though I arrived at the same conclusion, you post explains it perfectly. Thanks once again.

    . Do you mean to say that the 40W bulb will have a greater power than the 100W one?

    Thanks. But why can't we use P=I2R? Also, both the bulbs will have different V's, hence I don't think we should use P=V^2/R. As for the affirmation in bold- P=I2R and I is constant because of which R will be greater for the 100 W bulb. Now, V is directly proportional to R. Therefore the 100W...

    Hi, I found a similar question in a physics book and I also arrived at the 40W bulb being less bright. Here's my argument- Since the bulbs are in series, therefore the current will be same for both. Now, P=I2R, hence P is directly propotional to R as I2 is constant for both bulbs. Therefore, R...
