A galvanometer having a coil resistance of 100 Ω gives a full scale deflection, when a currect of 1 mA is passed through it. The value of the resistance, which can convert this galvanometer into ammeter giving a full scale deflection for a current of 10 A, is :
  • a)
    0.1 Ω
  • b)
  • c)
    0.01Ω
  • d)
Correct answer is option 'C'. Can you explain this answer?

Ig G = ( I – Ig)s
∴ 10–3 × 100 = (10 – 10–3) × S
∴  S ≈ 0.01 Ω
