R = 1Ω+(1/((1/(3Ω+3Ω))+(1/(3Ω+3Ω))))  R = 1Ω+(1/((1/(6Ω))+(1/(6Ω))))  R = 1Ω+3Ω = 4Ω  I = (V/R) = ((12V)/(4Ω)) = 3A
$$\mathrm{R}\:=\:\mathrm{1}\Omega+\frac{\mathrm{1}}{\frac{\mathrm{1}}{\mathrm{3}\Omega+\mathrm{3}\Omega}+\frac{\mathrm{1}}{\mathrm{3}\Omega+\mathrm{3}\Omega}} \\ $$$$\mathrm{R}\:=\:\mathrm{1}\Omega+\frac{\mathrm{1}}{\frac{\mathrm{1}}{\mathrm{6}\Omega}+\frac{\mathrm{1}}{\mathrm{6}\Omega}} \\ $$$$\mathrm{R}\:=\:\mathrm{1}\Omega+\mathrm{3}\Omega\:=\:\mathrm{4}\Omega \\ $$$$\mathrm{I}\:=\:\frac{\mathrm{V}}{\mathrm{R}}\:=\:\frac{\mathrm{12V}}{\mathrm{4}\Omega}\:=\:\mathrm{3A} \\ $$

It′s funny because we have a  resistance of 3Ω by using four  resistances of 3Ω.  In the real life, only one resistance  of 3Ω is enough to obtain 3Ω.
