Question

An ammeter A of finite resistance, and a resistor R are joined in series to an ideal cell C. A potentiometer P is joined in parallel to R. The ammeter reading is I0 and the potentiometer reading is V subscript 0 end subscript P is now replaced by a voltmeter of finite resistance. The ammeter reading now is I and the voltmeter reading is V

  1. I greater than I subscript 0 end subscript comma V less than V subscript 0 end subscript    
  2. I greater than I subscript 0 end subscript comma V equals V subscript 0 end subscript    
  3. I equals I subscript 0 end subscript comma V less than V subscript 0 end subscript    
  4. I less than I subscript 0 end subscript comma V equals V subscript 0 end subscript    

The correct answer is: I greater than I subscript 0 end subscript comma V less than V subscript 0 end subscript
