Screwdriver to both leads
>>
>>60155675
all it takes is a screwdriver and a courageous soul
>>
Don't joke about that man... My brother died that way.
>>
>>60155713
Too far mate
>>
>>60155675
You wait, it will decharge eventually.
>>
>>60155719
Sorry, sometimes it's easy to give dangerous advise online
>>
>>60155675
You can discharge it easily with some dirt in a bucket, as this acts as ground.
Just poke it in for a few seconds and it should be fine.
>>
>>60155675
honestly nobody likes to say it but if you urinate on it you can safely drain it almost instantly
>>
>>60155675
Especially for High voltage and High capacitance ones simply touch one lead with your left hand and the other lead on the right hand
>>
>>60155675
megger it and throw them at people
>>
>>60155675
Are you fucking retarded? Use a screwdriver, you mong.
>>
>>60155738
How dangerous is that shit even?
>>
my cousin put one of those on his tongue thinking it would just give him a little tingly sensation like a 9v battery and he spent 5 months in a coma in the hospital and now has permanent brain damage and had to have his tongue and part of his gums/teeth removed. he's so dumb now he can't even use a computer anymore so he had to get a smartphone instead.
>>
>>60155934
depends on the cap and your screwdriver.
>>
>>60155978
I see. I just don't understand electronics at all.
Will that short circuit it?
>>
Touch both of the leads and find out faggot
>>
>>60155983
yes, thus draining it, you can just use screwdriver, if you don't want a spark, use a resistor of appropriate value.
>>
>>60155967
You could have ended with something like "now he moderates /g/"
>>
>>60155675
use a resistor.
>>
>>60155675
Touch both contacts to a piece of grounded metal, i.e. pretty much any water faucet.

>enjoy your 3 months' free hot water
>>
>>60156069
I don't think it's 3 months, it's more like 16 days, but it depends on the faucet.
>>
>>60155675
Short out its leads you fucking idiot.

If you need it for a peak detector or some shit like that then put a resistor in parallel of a a suitable value for the decay time you want, alternatively put an N-channel MOSFET in parallel with the drain common to the capacitor and the source common to ground and apply a square wave signal of amplitude greater than Vgs(th) and at a suitable frequency and duty cycle to the gate to regularly short out the capacitor.
>>
I used to make home made tasers with these in disposable cameras
>Can you take my picture please?
>>
>>60155675
you can never go wrong with a resistor with a shitton of resistance between the leads
>>
>>60156069
>>60156168
>hot water
what?
>>
>>60156267
Actually you can.

If you have something like a 2200uF capacitor charged up to 240V and you try to discharge it through say a 1Mohm resistor you'll be in for a pretty fucking rude awakening if you don't leave that resistor on there for long enough. Just discharging that from 240V down to a much less dangerous 50V would take nearly an hour through that resistance.
>>
connect it to a lamp outlet
>>
>>60155967
I stucked on a Nintendo so charger,electricity tastes metallic.
>>
>>60156012
This. What a loss of oppurtinity.
>>
>>60155934
Don't short the ones you find in a defibrillator unless you're insulated.
Most capacitors you find are harmless.
>>
With your tongue.
>>
Study basic physics and stock up on a handful of different resistors.
>>
>>60155934
Multiply capacity in uF by voltage. If it's six figures or more, avoid using a screwdriver because the resulting arc can damage the terminals or throw bits of solder in your direction.

>>60155934
It's not for most things. They used to discharge CRT caps by shorting them.

If you're a massive pansy faggot you can get a large ceramic encapsulated 10 watt resistor or so and put it across the leads or some nichrome heating element wire should do the same. A pair of wires going into a jar of salt water will also work as long as they aren't shorted inside the jar.

This is weapons grade bullshit.
The only way it will drain is if it has a bleed capacitor across it in a circuit.
CAPACITORS CAN AND WILL HOLD THEIR CHARGE FOR YEARS

Screwdriver with an insulated handle, or a FUCK HUGE resistor depending on the size of the cap.
(Ive blown chunks out of a screwdriver discharging shit(kinda pissed, I liked that screwdriver))
>>
We used to charge 1000u caps to the maximum and then fused them to metal surfaces all across the campus
>>
>>60155675
Insert a resistor at its soldier points.

These aren't mine they belong to my professor

It's like 1000 capacitors and resistors

Is there an easy way to sort them? Like could I use a magnet to pick up the bigger ones and not the smaller ones?
>>
>>60161265
They'd gut you like a fish to recuperate costs.
>>60161272
Possibly. Use plastic over the mag to get different strengths. Also helps to get them off.

Someone accidently the capacitor drawers

Some of the resistors are u see the container and they got crushed but I can't see how bad it is because he told me to go sit down and we will "talk after class"

What's the voltage and capacity? These are the real questions.. Anything smaller than 10uF/50V electrolytic isn't worth worrying about. If larger just use a 10w+ resistor or make a bypass From the negative terminal(DC gnd) with some thick gauge wiring

youre a fucking retard, those caps aren't charged and even if they were you deserve getting shocked

stop being a faggot and pick up the mess you made

If you are asking that questionn you don't know what short-circuit means
