Five resistances are connected as shown in the figure. The effective resistance between the points A and B is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The given Wheatstone bridge is a balanced one.
In the given circuit, the ratio of resistances in the arms of the bridge is
Since, 
, hence the bridge is a balanced one.
Hence, 
resistance is avoided. The given circuit can be reduced as follows :
The 
and 
resistances are connected in series, hence circuit reduces to.
The 
and 
resistances are in parallel
