Hi, newbie here.
I want to build an electricity generator.
It would be based on a water wheel, to which I'd connect a multi-planetary gear system, to which I'd connect a rod magnet.
I'd found out that when you begin to extract electricity it creates a sort of resistance, and it lowers the RPM of the magnet/water wheel.
I'm trying to find out if there's a way to correlate the amount of wattage extracted to the resistance created, and hopefully estimate how much that would lower the RPM.
For example, if the magnet is spinning at 2000 RPM, with no appliance connected to the generator, then I'd connect an appliance rated at 2000W and begin using it - what resistance would that create, and what would be the RPM of the magnet?
I understand that as a newbie I may ask stupid or incomplete questions, but help me out here please;
For slightly more context: I'm ultimately trying to find out what force would need to be applied on the water wheel, so that when extracting electricty it would keep spinning despite the resistance created.
For example, let's say the generator is capable of supplying 10 outlets at 220V AC, with about 2000W each, or 20,000W total.
Well, I'd want to find out, in case I use all 10 outlets at once, powering 20,000W of appliances - how much resistance would be created, and what force/water pressure would need to be applied to the water wheel to prevent it from stopping?
Now this may be 2 questions in 1, I only provided the second one as bit of context.
Mainly I'd want to know how to calculate the resistance created.
Thank you.
