**1. The problem statement, all variables and given/known data**

Two bulbs rated 25 W - 110 V and 100 W - 110 V are connected in series to a 230 V supply. What will happen?

**2. Relevant equations**

p = vi. p = v2/r

**3. The attempt at a solution**

I am not sure I know how to interpret it correctly. To find the current through bulb 1, I did P1/V1 = 25/110 = .227, and for bulb 2 I did P2/V2 = 100/110 = .909. This can't be right because I1 must equal I2 since they are in series.

If I use the other formula p = v2/r and solve for resistance, i get a really big answer. i think i may be doing something wrong by plugging in 110 for v.
