Homework Statement
Two light bulbs are rated as 60 W and 75 W at 220 V. If these are connected in series to a source of 220 V, what will the power in each be? Assume a constant resistance for the light bulbs.
Homework Equations
W=VQ P=IV V=IR
The Attempt at a Solution
I was solving a similar question, which was dealing with bulbs connected in parallel. By dividing the work (W) by the Volt (V) I got the current (A), which seems a little strange to me since I thought I'd get the charge. Could anyone explain this please? (I then used V=IR and then P=IV to figure out the power dissipated) When it comes to light bulbs connected in series I don't know how to approach the problem or what differs between the bulbs that are connected in series and those that are connected in parallel.
