A potentiometer wire has length L for given cell of emf E, the balancing length is from the positive end of the wire. If the length of potentiometer wire is increased by , then for the same cell, the balance point is obtained at length
- A from positive end
- B from positive end
- C from positive end
- D from positive end
Answer & Solution
Correct Answer
(A) from positive end
Step-by-step Solution
Detailed explanation
For cell of emf E balancing length
(length of wire)
Increased length of wire =
Since, the cell is the same, therefore the new balancing length
= (new increased length)
Therefore, for the same cell the balance point will be as length from positive end.
(length of wire)
Increased length of wire =
Since, the cell is the same, therefore the new balancing length
= (new increased length)
Therefore, for the same cell the balance point will be as length from positive end.
