Question
Five resistors of given values are connected together as shown in the figure. The current in the arm BD will be
- Half the current in the arm ABC
- Zero
- Twice the current in the arm ABC
- Four times the current in the arm ABC
The correct answer is: Zero
This is a balanced Wheatstone bridge circuit. So potential at B and D will be same and no current flows through 4R resistance.
