Capacitor safety question?

I am working with an open capacitor that I built out of copper and was wondering; how do I choose a safe voltage and amperage. Meaning one that can easily be discharged and wont kill me but also has a somewhat strong electric field between the plates.

the changing and balance are usually included in the price on new tires the alignment shouldn't be over 100( unless 4w independent) 200 is a bit steep but not out of line. you might be able to get it cheaper. if you're just getting tires why are they selling a re-alignment?

You should get the balancing, realignment etc but not at Pep Boys. $200 is a rip off

If you have no dielectric between the two plates, there really isn't much of a danger per se. Then your concern would be the wires lighting on fire. Safe voltages are determined by the manufacturers through lots of testing, but that's because they can mass produce the model and have more than enough to dispose of through testing. You, on the other hand, have no such option since you have a single capacitor. So, as long as you stay away from using dielectrics, you should be fine. They are what more-or-less determines the energy limit of your capacitor. I would be more concerned about your wires if I were you.

Copper and what? I'll assume copper sheets separated by an insulator like glass. Amperage has little to do with this. Voltage you can determine in several ways. First, what is the max voltage you can apply to the capacitor without it arcing over. I don't know the details of your construction, so I can't guess at that. But it could be in the thousands of volts. But if you want to avoid shock hazard, you should keep the voltage below 40 volts. Voltages above that can be hazardous. Not only from the cap, but from your charging circuit, what ever that is. Electric field is determined by the voltage and by the spacing between the plates. If you have 40 volts on the cap and the spacing is 1 mm, then the electric field is just E 40V/1mm 40V/(0.001m) 40000 volts per meter, which is equivalent to 40000 Newtons/coulomb

You kinda have to get the tires balanced before they get mounted. Your car may or may not need an alignment. Does your car lean left or right when you put your hands off the steering wheel while driving? If it does it needs one. A lot of tire places checks them for free in my area. If you don't get an alignment and your car needs one you tire won't wear evenly and you'll have to replace them sooner then expected. Just remember you always get what you pay for - this rule applies to any product or service.
