While measuring the unknown resistance the help of slide wire bridge a greatest accuracy can be achieved when__________________?
Aa most sensitive galvanometer is used
Bthe balance point is close to the middle of the wire
Ca steady voltage cell is used
Da high resistance box is used in one of its gap
Correct answer
B. the balance point is close to the middle of the wire
Explanation
the balance point is close to the middle of the wire is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
