Four resistances 10 W, 5 W, 7 W and 3 W are connected so that they form the sides of a rectangle AB, BC, CD and DA respectively. Another resistance of 10 W is connected across the diagonal AC. The equivalent resistance between A and B is [EAMCET (Med.) 2000]
A) 2 W
B) 5 W
C) 7 W
D) 10 W
Correct Answer:
B
Solution :
The figure can be drawn as follows Þ \[{{R}_{AB}}=5\Omega \].
