Question by snapshot1919: can a 50v windmill generator power a 25watt lightbulb?
for a science project im doing a project and it is: which windmill turbine will power the most electricity? Will this work?

if you generate 50v i’m assuming d.c. you’ll probably get the bulb to glow a little you need to step th voltage down with a potentiometer to 12 or 16 volts and use automotive lamps or headlights unless you are generating a.c. then you’ll probably be ok with standard 120volt bulbs.

There are too many unknown variables to give an accurate answer to your questions. Just because a windmill generator can produce 50v at some level of wind speed doesn’t mean it can produce 25 watts of electrical power, which is the minimum you need to operate a lightbulb with a 50v filament… and good luck trying to find one of those!
But, let’s just suppose the windmill can produce a half ampere of current with a terminal voltage of fifty volts: that’s 25 watts, so it will be enough to power a 25watt lightbulb that operates from 50v. In other words, it would work.
As to which windmill turbine will power the most electricity, that depends on a whole bunch of other factors like minimum, maximum and average wind speed, area swept by the windmill blades, number of blades, pitch and rate of rotation of the blades, just to name a few of the things you need to consider. There is no one windmill design or windmill turbine that is suitable for all purposes and all locations.
Do some real research (crack a few books at the library, look at some real windmills on the Internet, ask a lot of questions after you find out what questions to ask) before you even think about a science project. When I did science projects in school, I always had a pretty good idea what the results would be from research I did before actually starting the project. That helps to prevent nasty surprises just before the project is due for submission and grading.

If that windmill is creating at least 1/2 Amp of current, then yes. Power=voltage*current
