I have figured this out before and I feel stupid asking for help. I am trying to make a 12volt 2 ohm resistance dummy load. I have been sick and my mind isn't all together. Any help would be appreciated. Thanks

12V @ 2R => 12x12/2 = 72W.
14.4V @ 2R => 104W.

Hence say two 1 Ohm 50W resistors in series.
Or five 10 Ohm 20W in parallel.

They'll get hot so maybe using more resistors is desirable...
