This might be a hairbrained scheme, but need to check this.
If I have a capacitor bank consisting of 20 3300uF capacitors, that should give me 66F right?
If I charge this bank to 15V that should be 7425 Joules of energy, + or - the 20% tolerance of the caps.
Since 1J = 1W/S[econds] I should be able to draw 7425W for 1S or 1W for 7425S. Am I right so far?
Ok If I have a circuit that draws 500mA or 7.5W, I should be able to power it for 990S, or 16.5 minutes, disregarding losses. Realistically I would expect it to work no longer than 5-7 min.
Have I done the math right?
BTW this is not a homework question, it is for a project I am currently working on.
