## Homework Statement

Two electric bulbs,each designed to operate with a power of 500 watt is connected in series on a 220 volt line.Now if they are connected to a line of 110v then the power generated by each bulb is??

## Homework Equations

## The Attempt at a Solution

When i solve it i get more variables that equations.

The equations that i have prepared are--

500=I

^{2}R

_{1}

500=I

^{2}R

_{2}

if i divide these equations i get R

_{1}=R

_{2}.But that is not possible.What is wrong in dividing these equations??

next--

220/(R

_{1}+R

_{2})=I

I am not able to find any value here.

plz help
