4 Capacitors in Parallel

  1. I was wondering how long would it take to charge a capacitor at 5volts if there are 4 parallel. This is the details on the Capacitors. 330v 120uF each. So what is the best way to charge them by usb which gives me 5v or using a 9 volt battery and for how long.

    If there is no series resistance I would think it would just takes few seconds, or less.
     
  6. It depends on the resistance, both of the wires and the battery/adapter. If you use a Pb battery, I think it takes just fractions of a second
