- 12 V
- 6 V
- 4 V
- 2 V
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Using the principles of a balanced Wheatstone bridge, the ratio of the resistances leads to the determination of the voltage value, which comes out to be 2 V.
Thus, the correct answer is option (4).
