I've been using this site to calculate capacitor charging: http://mustcalculate.com/electronics/capacitorchargeanddischarge.php?vfrom=0&vto=29.99&vs=30&c=10000u&time=.2 And according to it it requires 12 amps to charge a 10000 uf capacitor to 30v in .2 seconds. What properties of a transformer...

Maybe my google-fu is lacking, but for DC-DC switchers, there seems to be two types: Ones that have the right voltage, but they are limited to 5 Amps of input current at most, and ones that require 12 volts input current but can support high current. The LED power supply circuits I saw needed...

I just had someone explain to me that if you have a transformer with a higher number of wrappings around the secondary coil, then the voltage will be increased by the proportion of coils. So would that mean if I ran the battery voltage through a transformer where the secondary coil had 5-6 times...

Wires will be in parallel. Charging time should be under .2 seconds. By my calculations, each wire will heat up by about 448 degrees C within 1 millisecond when discharged (assuming resistance is low enough) which (I think) is more than enough for what I need. The only issue with the Marx...

Hi, I'm trying to build a capacitor charger that can charge a capacitor to a higher voltage than the battery voltage I have. When reading up on charging capacitors, the simplest method seems to be wiring something similar to the capacitor charger for a camera flash. Unfortunately, a camera flash...

I came here mainly to figure out how to create a certain circuit. I don't have any other physics based issues, and I'm doubtful I could provide any helpful info to anyone else for stuff.

Hey, I found this site while trying to figure out an electrical circuit problem. I'm new to electronics, but I've been using a 3d printer that I built myself for a while now, so I'm already involved in the material sciences and programming. No formal education yet.
