Subject: [alt-beam] Re: caps
Capasitors in series work almost like resistors in parallel.
1. 2 2.5V 1F caps in series can handle 5V with a 0.5F capacity
2. In parallel they can handle 2.5V with a 2F capacity
3. The bigger the cap the longer the current output will last. You won't be
able to get more or less current.
