What's the minimum size of a generator? (Wanna use it in my science project.)

Tear apart an old discarded electronic object. Probably you'll need something far exceeding 1 microfarad (uf). However,

For series, multiply by voltage rating of "bulb"


Connected in parallel establishes proportionally higher cap but same voltage; series, proportionally higher voltage but lower cap. However on account of leakage and small diffs in cap series might not charge uniformly


We admire your determination

Thanks for your replies.
I've changed the idea, though. . .

Generators with power supply capacities of 5kW to 50kW can be used for personal and home use markets.
