I am constructing a simple circuit to convert AC power from the wall to a 10V DC power across a load. I am fairly new at this though, so I have a question about how much power a capacitor can handle. I will be using a couple of 100μF capacitors. These are just your basic capacitors, purchased at your local university for college labs.
