Yep, putting them in parallel increases the group power dissipation and lowers group resistance. You still need to calculate power dissipation separately.
$$R1 \parallel R2 = \frac{R_{1}R_{2}}{R_{1}+R_{2}}$$
$$P = IV = I^{2}R = \frac{V^{2}}{R}$$
If you have N resistors in parallel and they are...
Um, Staples, Office Depot, Amazon, or Newegg (or Google Shopping)?
Not a bad option for personal projects. Shipping from Grainger or McMaster Carr will be more than the cost of the $5 12-pen box (which puts the springs at $0.41 apiece).
I have no idea where to order these for production.
A good solution will be 'not too hard" to provide once the true requirement is fully described :-).
At present your description covers a range of possible requirements. Can you provide more details and/or a circuit diagram with suitable notes?

Added some latex to that for the hell of it...but the answer is not that coherent, and fixing all the prose would take forever. :(
@DanielGrillo, @Kortuk, make speedcontroller and esc go to speed-controller, [tag:electronic-speed-controller] or the like (they don't exist currently, however).
Looks like Russell (of PIClist fame) has shown up to answer a few questions. He is an expert at small switchers and LED lighting, and broadly knowledgeable about many other subjects. Let
Hi, how are you?
Im looking for a good guide to design a colpitts oscillator. Also if you know you can submit ur explanation?
Im suppose to do one with a 1.63MHz frequency so im looking but i want your help too
@Nick - That looks like a bad homework question to me.
@All - If you see a question or answer with broken dollar signs causing LaTeX markup where it wasn't intended, like @Tyblu's link to mine (electronics.stackexchange.com/questions/11068/…), you can replace those dollar signs with the HTML code $, just like replacing < or > signs with < / < or > / > can sometimes fix problems with markdown.
o_O
No you can't.
After trying it, the javascript still triggers on $ ... what should we do about this?
I'm coming from a computer science background, and will be writing some software to automate battery testing. I have background in math, but little to none in physics or electronics. Please consider this in your answers.
That said, how would I go about testing the internal resistance of a small ...
@NickT - $\$$ works - You get a TeX-ified dollar sign. Would be hard to explain. Also, I really don't want to pollute the front page with a bunch of dollar-sign edits. Is there a better way to do these edits?
The current LaTeX escapes of $ ... $ need to be changed.
Several questions/answers have two dollar signs in the text somewhere. E&R has a number of questions with prices, and we usually use USD, represented by the $ character, as the monetary unit. This has lead to a number of broken que...

@Dan - It was a joke, you showed up, I figured you'd see it and laugh. I took some extra liberties because it's just chat. Instead, hobod, Stefa, and drach showed up from other sites to investigate Nick's disparagement of moderators....whoops! I didn't realize that flags here propagated like that. At least Stefa got the joke...
Lol. I often occasionally through old National Geographics; it's amazing how much more politically correct advertising is now than it was then. Full blog link: http://www.electronicsweekly.com/blogs/david-manners-semiconductor-blog/2007/05/best-ever-semiconductor-ad.html

@reemrevnivek I didn't admonish anyone for flagging negatively. I merely instructed him what he should do with the questions that he doesn't like. There's no way for the mods to know about questions that are no good.
@DanielGrillo, also, if you leave someone a comment on their answer and then delete it they can still see it. I waiting to delete that pickit 3 also, I think your feedback and waiting to give them 12 or more hours to respond is a good case
I cleared out 12 flags this morning.
@DanielGrillo, You disappeared for a little while, how are things going?
