I called DigiKey to order some components... so i was like
"i need a 47k resistor."
and she was like
"1% or 5%"
i knew what that was, so i said 5% (usually doesn't make a difference does it?)
then she said
"surface mount or through hole"
i guessed through hole
then she said "what wattage?"
i was like ummm i'll call you back
if i'm running a circuit on 3v (battery) then do i need 1W? 1/4W? whats the deal with that?
i'm fairly new, but i'm trying to learn via kits and stuff like that.
any info would be great
PS. i use the same msg board for my site, PHPBB2 is great!
