  • a)
    I/I0 = 2/11
  • b)
    I/I0 = 1/11
  • c)
    I/I0 = 4/11
  • d)
    I/I0 = 3/11
Correct answer is option 'B'. Can you explain this answer?

We have a galvanometer of resistance 25Ω. It is shunted by a 2.5Ωwire...
Calculation of Total Current
- The total resistance in the circuit is given by R = 25Ω + 2.5Ω = 27.5Ω.
- Let the total current in the circuit be I0.

Calculation of Current through Galvanometer
- The current passing through the galvanometer is given by I = V/Rg, where Rg is the resistance of the galvanometer.
- Since the galvanometer is shunted by a 2.5Ω wire, the total resistance seen by the galvanometer is 25Ω.
- Therefore, the current passing through the galvanometer is I = V/25Ω.

Calculation of Fraction of Current through Galvanometer
- The fraction of the total current passing through the galvanometer is given by I/I0 = (V/25Ω) / (V/27.5Ω) = 27.5/25 = 11/10 = 1/11.
Therefore, the correct answer is option 'B' which states that the part of the total current that flows through the galvanometer is I/I0 = 1/11.
