If you would please check my math, I would appreciate it...
Goal: 1.25Ω @ 2w power capability
Wired: 4X 5Ω 1/2w resistors in parallel
1/5 + 1/5 + 1/5 + 1/5 = .8
1/.8 = Rt, 1/.8 = 1.25Ω
1/2(w) + 1/2(w) + 1/2(w) + 1/2(w) = 2(w) power rating
Final answer: 1.25Ω @ 2w power rating
Is this correct please?
Thanks,
Andrew
