make a 1 Watt resistor out of two 0.5w resistors ?

How?

Resistors don't come in watts...  So, WAT.jpg?

Put them in parallel.

Quoted:

Each resistor will carry half of the current.





Each resistor should be twice the target value. I.e. if you want a 4 ohm resistor parallel two 8 ohm resistors.

This is correct.


 



Or you could parallel four .25 watt resistors, just make sure the values of each resistor is four time the target value, i.e. if you want a 4 ohm 1 watt resistor then parallel four 16 ohm .25 watt resistors.

Yeah, actually they are rated in watts.

No.  Resistance will be target, but capability to handle amperage will not, and resistance will only equal target in series.  

You could decrease amperage through a single resistor by putting them in parallel, but that effectively lowers parallel resistance to below the lowest single resistor value.

Never mind: already covered by Paul!

Yes. If placed in series, each resistor should be half the desired value. If in parallel, each should be twice the desired value.

If you place them side-by side, leave a small air gap between them to allow for air flow.

If they are not of equal value, one will dissipate more power than the other.

Two 1/2 watt resistors, either series or parallel wired will work.  Just need to calculate required resistor values. (hint, 1/2x value if series, 2x value if parallel).

Or series of half the target value works as well.

No.

This is how you burn down houses.

You will have target resistance, but not amperage capability.

Look, if you're running E, I, R numbers, it works out.  But E, I, R numbers on a piece of paper don't take into account safety.  Will you get target resistance?  Yes.  Will you get the same amperage handling capability?  No.

Electrical engineering is fuckin bullshit.

My grandpa would just take a whole shitpile of resisters from TVs at the local dump and sotter em up into a big ball by dribblin lead all over em.

And then run bare copper watter pipes from the fuse box to the resisters

Never had any problems so fuck you.

This :






if you have 1/2w 1ohm resistors.
paralleling them will obtain 1w 1/2ohm resistor, so if you want the
resistance back 1ohm, you need another 2 parallelled resistors and put
them in series, so in order to get 1w 1ohm resistor, you need 4 of 1/2w
1ohm resistors.



--\/\/\/-- = 1/2w, 1 ohm



|--\/\/\/--|

-|            |- = 1w, 1/2 ohm

|--\/\/\/--|



|--\/\/\/--.--\/\/\/--|

-|                           |- = 1w, 1 ohm

|--\/\/\/--.--\/\/\/--|
