Grouping of Resistances
question_answer
In the network shown in the figure, each of the resistance is equal to \[2\,\Omega \]. The resistance between the points A and B is [CBSE PMT 1995]
A) \[1\,\Omega \]
B) \[4\,\Omega \]
C) \[3\,\Omega \]
D) \[2\,\Omega \]
Correct Answer:
D
Solution :
The equivalent circuits are as shown below Clearly, the circuit is a balanced Wheatstone bridge. So effective resistance between A and B is \[2\,\Omega \].
