Why does everyone hate capacitors?

[CBFryman2 5,000+ posts]

A capacitor will charge to its capacitance value and while it's doing so, 1/2 of the energy will be dissipated as heat. And while it's discharging, 1/2 of the energy will be dissipated as heat. It's the law on conservation.
And typical caps have very low relative energy storage capacity.

Agian, you dont add a cap and expect more current, you add a cap to smooth voltage.

Guys with huge alternators and big battery banks still have voltage flicker when the amps suddenly draw gobs of current.

How can we fix this?

1. Try a cap. Install it properly, either it works or not.

2. Isolate your stereo system electrical from the car electrical system. Run your

car stock, ie stock battery and ALT. Install a second HO ALT with battery array

to drive the stereo. Two isolated systems, no flicker ever.

I have some ideas for 'regulated headlights' /// heehee ///

I'm not going to participate in a technical battle. I'm tired of in depth useless technical battles. Caps have there place, just not in the instance where people generally use them. Your 2nd idea is not practical in most aplications and it still doenst solve the voltage flicker problem.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

As far as your headlights are concerned, it solves the problem perfectly...

I'm from the 'hands-on' camp moreso than theory. To solve problems I would

probably just try the ideas to see if the fix can be resolved quickly without using brainpower.

I'm not arguing for or against caps.

I never said it adds "more" current. I said I don't like the addition of capacitors off the bat, because of the energy dissipation.

I love the smooths voltage discussion, sure it "smooths" voltage at a relatively low level as compared to a high load causing dimming, which isn't significant. Easily seen through energy storage of a cap vs energy needed to actually significantly "smooth".

Anyway, I like thylantyr's regulated headlight ideas. I think the audio capacitor camp should jump bandwagons to that //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

That was said from the begining.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
