oops looks like that diagram didnt translate well, here

ignore the asterisks. they are there for spacing

What is the equivalent resistance for the resistors in the figure shown above?
-1.3Ω
-2.2Ω*
-3.0Ω
-12.0Ω
please confirm :)

looks like 9 in parallel with 3
1 / r = (1 / 9) + (1 / 3)
multiplying by 9r ... 9 = r + 3 r
1 / r = (1 / 9) + (1 / 3)
multiplying by 9r ... 9 = r + 3 r
