Question

An ammeter of range 5 A is to be converted into an ammeter of range 10 V. If the resistance of ammeter be 0.1 capital omega, then what resistance should be converted in series with it?

  1. 1.1 capital omega    
  2. 1.9 capital omega    
  3. 2.1 capital omega    
  4. 4.9 capital omega    

The correct answer is: 1.9 capital omega


    R = (V/I) – GA = 10/5 – 0.1 = 1.9 W
