I agree with Pommie,I can't see how a 200Ω (R4) resistor in parallel with a 500Ω (R5+R6) can dissipate less power. My guess is R6 - maybe I should do the maths.
Edit, I make it,
hi Mike,Something wrong there Eric,
I for R1 is Sqrt(4/100) = 200mA
V R1 = 0.2*100 = 20V
V R2 = 30-20 = 10V
W R2 = 10^2/200 = 0.5W
Weird thing is the values for R4-6 match mine.
Eric, the voltages don’t tie up.hi Mike,
I agree, something amiss.?
Added more results to sim diagram.
As I am still studying LTSpice, I just try some posters diagrams in order to learn and find the 'funnies' in the sim.
