I am rectifying the mains voltage which is 120V @ 5A with a full wave rectifier. How many volts and microfarads will my capacitor need to smooth out my rectified DC?

Are there any online calculators for this?

Thank you in advance!

I have two senior design classes and right now I'm prepping for the first one in the fall semester. I was thinking about implementing an RSA Stream Cipher using shift registers. Is this too easy?

I own a fitness center and I'd like to understand how much my treadmills are costing to operate.

Each is 120 volts and 15 amps. Does this mean that each is consuming 1.725 Kw per hour and therefore 41.4 Kw per day (we're open 24 hours).

Or, is each consuming some nominal amount of power when not in use and then more when someone is using it.

Finally, if it consumes more power when someone is on it, does it consume more power the faster someone walks/runs and the more that person weighs (because the treadmill is "working harder" at higher speeds)?

Bonus points are give for helping me calculate an exact number if we assume the avg treadmill has a 180 pound person walking/running at 5 mph (out of 15 max) for an average of 5 hours a day :)

Thanks!!!!
