capacitor help

[nickm 10+ year member]

I was given 2 capacitors, How can I find out what size they are? They have no writing on them. except the word NICE across them.

want help with those? Throw them away they wont do ya much good even if they do work.... that is a misconception that they help with Sq, sure they may prevent SOME dimming but actually make ure system sound shittier so needless to say throw them away.... caps ****...

Just throwing a number out there, they fit the general size that 1F electrolytics *usually* are for "car audio" purposes, but there's really no way to tell without some fancy test equipment //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

COOL, I have some shiny paper weights //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Thanks anyway //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

EXPENSIVE test equipment

*Car battery

*10 cent resistor

*Voltmeter

*Calculator

You can get a very good guess. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

^^ Indeed. But add stopwatch to that list.

Charge the cap through a 100 ohm resistor off your 12V battery. Time how long it takes for the cap's voltage to get to 8 volts. The capacitance (in Farads) = time / 100.

well now. I guess I am rich. Because I have some of that expensive equipment. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
