in series combination
Req = R1+R2+R3 ..
in parallel combination
Req = 1/R1 + 1/R2 + 1/R3
Since the 4 ohm and the 6ohm resistors are in series, the equivalent resistance of the combination of those two resistors is 10 ohm
The 9 ohm and 8 ohm resistors are in parallel; their equivalent resistance is 4.24 ohm .
The equivalent resistances of the parallel combination (9 ohm and 8 ohm) and the series combination (4 ohm and the 6 ohm) are in parallel; therefore, their equivalent resistance is 2.98 ohm.
The 2.98 ohm combination is in series with the 3 ohm resistor, so that equivalent resistance is 5.98 ohm.
Finally, the 5.98 ohm combination and the 20 ohm resistor are in parallel, so the equivalent resistance between the
points A and B is 4.6 ohm
