Find the equivalent resistance between the points A and B of the network shown in figure ( file has been attached )
Homework Equations
Req( series) = R1+ R2 + R3 .. + Rn
1/Req ( parallel) = 1/R1 + 1/R2 + 1/R3 .. + 1/Rn
The Attempt at a Solution
We have to find the equivalent resistance between a and b.
The way I solved it was :
1) the second ( from left )4 ohm and the 3 ohm are connected in series, so Req = 7 ohm.
2) now the 7 ohm and 2 ohm are connected in parallel, so Req = 1.56 ohm
3) the remaining 4 ohm and 1.56 are connected in series, so Req = 4.56 ohm.
But this answer is wrong..According to the book,
The 2 ohm resistance is connected in parallel with the 3 ohm resistor. Their equivalent resistance is 2 ohm which is connected in series with the first 4 ohm resistor from left. Thus equivalent resistance between A and B is 6 ohm.
Please help :/
