| The energy in joules (watt-second) stored in a capacitor is given by 1/2xCxV^2. For a .033 farad capacitor at 200 volts that is equal to 660 joules. This is not a large amount of energy, but can be useful. If it was all used in one second, for instance, it would provide .9 horsepower. Or .09 horsepower over ten seconds. Or 900 horsepower in one millisecond. It all depends on how you use it. One of the neat things about capacitors is that the energy stored for a given capacitor depends only one the voltage and it doesn't matter how you get to that voltage.
By the way, the energy stored in an (ideal) inductor is given by 1/2xLxI^2. Inductors tend to be less ideal than capacitors. |
