ok resistor question number 2....

[oldslowchevy]

i have looked..... the information i have found seems to contricdit it self... alot.


does a 1/2 watt resistor only take a 1/2 a watt away or will it only allow a 1/2 watt though?

better example, if i have 5 watts and i install a 1/2 100 ohm resistor will i then have 4.5 watts, or only a half of a watt?


the internet is not my friend:headbang, but you guys are

Read this and learn. The knowledge you gain will stay with you for a lot longer than just being handed the answer.

(Sorry, but this is the way my Father forced me to find my own answers)

i did read this, much of it i understand much is wayyyyy beyond me. sadly if my multimeter wasn't crushed i would see what i needed. i don't have the money for a new meter and it is not cost effective for me to order what i need for $1.25 + 12.95 for shipping and handling for 1 resistor.

really though the way my day is going i am thinking about giving up. 3/4 of the day is though and i have gotten nothing acomplished yet....:headbang
i hate days like this.

You need to figure the amount of current passing through that resistor. You know the ohmic value (I hope), and you're specifying that the resistor is rated at 1/2 watt. I = sqrt(P/R).

I responded on your earlier question, and the answer should still be there...

Resistors don't "take away" any watts; they dissipate them as part of the entire circuit.
