Answer:12ohm
Explanation:
R3 and R4 are in please because amount of current flowing through them is same. It means they are in series
Rs=R3+R4
=6+4. =10 ohm
Now Replacing R3 andR4 by a single resistor Rs connected in parallel to our to as the amount of current flowing through them resistors is different.
1/Rp= 1/10+1/10
=5ohm
Now replacing the R1 and R2,R3 andR4 with Rp.
R1and Rp are connected in series as the amount of current flowing through them is same .
Rf=R1+Rp
=7+5. =12 ohm
Hope it helps
