Somebody please double check my homework.

I got four 2400 MFD electrolytic caps and just selected a 10 ohm 200
watt power resistor from the scrap bin. I get 0.48 seconds to charge
these caps through the resistor using a very simple formula I found:

CHARGE TIME = 5*R*C

I'm setting a time delay relay to .5 seconds before shorting out the
resistor.
