I really don't understand your numbers. How could a 6Ω resister added to the mix possibly work?

If we start with 7.2V and a 2.2Ω

atty we get about 22 watts (ouch). Adding a 6Ω resistor (8.2Ω total) we get 6.3 watts, but isn't the 6Ω resistor dissipating 73% of those watts leaving the

atty itself at a paltry 4.6 watts?

Adding 1Ω to the mix makes sense to me. 7.2V @ 3.2Ω = 16.2 watts. The 1Ω resistor is dissipating 31% of the watts leaving the

atty at about a nice 11 watts.

Am I not understanding this correctly?
