Each bulb will have 60V across it if connected to 240V. Here is the question word for word: Bill and Mary are discussing the lighting for their living room. At present they have four 60W, 240V light bulbs in parallel. Bill suggests that it might be cheaper to replace these four bulbs wired in series. If this was to be done, what would be the voltage and power rating of each of the new bulbs they would need in order to produce the same amount of power. Thanks for the quick replies BTW.

I think I'm suppposed to find the first option. I think I'm misinterpreting the question in my textbook. I worked out that changing the voltage to 960V while keeping the same power rating will work. Right? But I think it's the wrong answer cause the question is asking for a different power rating.

The question: Four 60W, 240V light bulbs are connected in parallel. If these lights were to be placed in series, what voltage and power rating would each have to be in order to produce the same amount of power? I know I'm meant to explain what I've tried but the confusing thing is that if 60W light bulbs are placed in series, each one would have 60v thus 1A will flow through so the power would be the same as the parallel circuit? Thanks for the help!
