they are parallel
yeah u r right pranshutripathi
ok
thnks i only giving suggestion
thanks....but mine ans is wrong...sorry
but here ur calculation is wrong bro

here
given
R1 = 1 ohm
R2 = 1ohm
R3 = 1ohm
R4= 1ohm
since R1 and R2 is in parallel combination
1/Rs = 1/1 + 1/1
=} 1+1/1
=) 2/1 =) Rs = 1/2
similarly
R3 and R4 are in parallel therefore
1/Re = 1/1 + 1/1 =)Re =1/ 2
now Rs and Re are in series combination
R' == Rs + Re
== 1/2 +1/2
= 2/2 = 1 ohm
hence the 1 ohm will be its effective resistance
