Q. Five resistors of given values are connected together as shown in the figure. The current in the arm $BD$ will be
A) Half the current in the arm $ABC$
B) Zero
C) Twice the current in the arm $ABC$
D) Four times the current in the arm $ABC$
Explanation
(b) This is a balanced Wheatstone bridge circuit. So potential at $B$ and $D$ will be same and no current flows through $4R$ resistance
