The diagram above illustrates the conversion of a galvanometer of resistance 29 to an ammeter. The galvanometer gives a full-scale deflection for a current of 10mA. Calculate the value of R.

  • A 2.0 x 103 Ω
  • B 2.0 x 102 Ω
  • C 2.0 x 10-1 Ω
  • D 2.0 x 10-2 Ω
  • E 2.0 x 10-3 Ω

The correct answer is E. 2.0 x 10-3 Ω
