Finding +and- on a cap

[Sabrewings]

actualls a microfarad it used to measure any capacitor. go to walmart and look at there amp kist that comes with a cap. it says 500 microfarads.

Then it's a weak as hell cap. A 500 microfarad capacitor would be about the size of a USB drive.

i dont know about microfarads but i always thought caps were sold in .5 farad or 1 farad increments (.5's are small caps)

reinke LOL at your drugged up comment im guilty of that myself...after a night of drinkin or whatever come home hit the forums and start flaming people haha...the world of internet hatin' its a victim-less crime!

In a small to moderate system caps absolutely do help, they are essentially batteries but they charge up and discharge MUCH faster than a battery and will hold a voltage equivalent to your charging system (not 12V like batteries)...if your into competition and you need a HUGE amount if current for a relatively short amount of time (about 1 minute) than multiple batteries will provide that to you. Sometimes batteries can appear they are helping, but you soon find out they are not helping when your alternator burns out on you way sooner than in should...

Sabrewings i guess you are right because i just typed in the simple term "500 microfarads to farads" in google search and google calculator gave me the result of "500 microfarads = 0.0005 farads"
