if you are connecting two resistances in series of 5 ohms each your equivalent resistance will be \[R=R _{1}+R _{2}=5+5=10 \Omega\] and if connected in parallel then \[R=\frac{ R _{1} R _{2} }{ R _{1}+R _{2}}=\frac{ 5*5 }{ 5+5 }=2.5 \Omega\]

thanks, but the question says, two resistance of 5 ohms each connected in series and then connected in parallel to a 0.5 ohms resistance. what is the equivalent resistance ?

well, then how those two connections are made, does it say 5, 5 of series and 5,5 of parallel are in series or in parallel?

if yes then you've got two equivalent resistances just add them 10+2.5=12.5 ohms
