Except 35 ohms and 12 volts is NOT 4 watts. It's 4 AMPS.
And watts is volts X amps, so the circuit is consuming not 4.105
watts, but 12X 4.105 watts which is something closer to 49 or 50
watts.

I used the calculator here to check my work and the 'solve for power'
section says 35.07541 ohms @ 12v = 4.10544 watts.
