I knew the ballpark. I knew it had to be close to 33 and 4 but I didn't know the exact number and I needed an answer accurate to the 3rd decimal place.
It's for a scavenger hunt and the answers are clues to the next item on the list.

Maybe the 'Yellow' items illuminate (i.e. Are lamps or LEDs)? And maybe the 'Red' items are resistors. Does that throw a different light on the question? Sorry for the bad pun!
In rference to 12 volts and 35 ohhms. V over R =3D Amps So 12/35 =3D 0.34 amps. And Volts times Amps =3D Watts So 12 x 0.34 =3D 4.1 watts. Or you can do it another way; Amps squared times R. So (0.34 x 0.34) times 35 =3D 4.1 watts.! Check! Or another way again; Voltage squred divided by R. So (12 x12) divided by 35 =3D 144/35 =3D4.1 watts. Check!
If I am thinking correctly, the answer is readily apparant with 2 seconds of thinking and almost no calculations. "Distance" from one conder to the opposite is 3 resistors = 3 ohoms. But there are 4 different paths which are all equal by symmetry -- so like 4
3-ohm paths in paralle or 3/4 ohms total.Took me 100 times as long to write it out as to solve it...
