Seven resistances are connected as shown in the figure. The equivalent resistance between A and B is [MP PET 2000]
A) 3 W
B) 4 W
C) 4.5 W
D) 5 W
Correct Answer:
B
Solution :
The given circuit can be simplified as follows Now it is a balance Wheatstone bridge. So, Þ \[{{R}_{AB}}=\frac{8\times 8}{8+8}=\frac{64}{16}=4\Omega \]
