In an experiment to measure the internal resistance of a cell, by a potentiometer, it is found that the balance point is at a length of 2 m, when the cell is shunted by a 5 Ω resistance and is at a length of 3m when the cell is shunted by a 10 Ω resistance. The internal resistance of the cell is
  • a)
    1 Ω
  • b)
    1.5 Ω
  • c)
    10 Ω
  • d)
    15 Ω
Correct answer is option 'C'. Can you explain this answer?

Given Data:
- Balance point at 2m with 5Ω shunt
- Balance point at 3m with 10Ω shunt

Calculations:
- Let the internal resistance of the cell be 'r' Ω
- Using the balance point formula, we have:
- (2/r) = 5
- (3/r) = 10
- Solving the above equations, we get:
- r = 10Ω
Therefore, the internal resistance of the cell is 10Ω. Hence, the correct answer is option 'c'.
