Fun with ultracapacitors!!

Don't do anything I did in this video. These capacitors are not designed to be shorted and doing so is dangerous. And no, you cannot make a welder out of these. I got hold of some 2600F capacitors that can dump hundreds of amps. Normally these are used in electric cars to handle sudden stops and starts. Instead, I use them to vaporize bits of metal, and show you the 3 most important capacitor equations along the way. Ultracapacitors on Amazon: www.amazon.com/exec/obidos/ASI...

Good conclusion XD

[@edgeeffect]

When I was a kid, I had an electronics textbook that said that a 1 Farad capacitor would be the size of a house if it was even possible to make one...... 45 years later - say hello to 2600 Farads!

[@VSSFantastic]

really all it takes is to play around with the surface area and the distance between the two plates of the capacitor, at the time they probably didnt have the methods required to make the tolerance required for small distances as they have today

[@cocosloan3748]

But is this capacitor same in properties like 1F block kapacitor? No!

[@RichFreeman]

These aren't capacitors. They have way more internal resistance. If he touched the leads on an actual capacitors of this capacity I believe the wires would turn to plasma. Just look at videos of railguns and such.

[@brandysigmon9066]

Thanks for your knowledge and the vids you do

[@benjaminthomas6547]

isn't it strange how the energy formula for a capacitor is so similar to the kinetic energy formula? I wonder why that is..

[@NotLegato]

because you get the result by integrating the infinitesimal increments of energy, which for something int. x dx becomes 1/2 x^2, and just has another coefficient. this is true for a lot of physics formulae.

[@chanakyasinha8046]

Because electrons have speed foool

[@benmusgrove9465]

I think it’s because the energy stored by a capacitor is the area under a voltage-charge graph. The area of a triangle is 0.5 * base * height so energy stored is 0.5 * charge * voltage. The gradient is also equivalent to the capacitance (charge/voltage).

[@billymaroko3736]

[@JoshuaC0rbit]

What kind of coil gun could you build with capacitors like that?

[@RichFreeman]

Wouldn't these have too much resistance for that? I need to look up the ESR of actual capacitors.

[@TheAmazingTechZone2]

For people who are wondering if they will die from touching those wires... If you touch the wires, you will not get killed due to the fact that the capacitor's voltage is very low. Think of the human skin as a resistor. In order to find out how many amps are going through the body, we could use Ohm's Law (Voltage/Resistance = Current). The average human skin is around 10k - 30k Ohm, depending on how wet your fingers are. In this example the caps are about 9 volts and let's say the resistance of our fingers are pretty dry and are about 10k Ohm. (9 volts/ 10000 Ohm = 0.0009 Amps) 0.9 mA won't be enough to even give you a slight tingle. In conclusion, these capacitor are very low voltage so they can't kill you or even give you a slight tingle.
