Question

I and V are respectively the current and voltage in a metal wire of resistance 'R'. Two I- V graphs at two different temperatures T subscript 1 end subscript and T subscript 2 end subscript are given in the graph. Then,

  1. T subscript 1 end subscript equals T subscript 2 end subscript    
  2. T subscript 1 end subscript greater than T subscript 2 end subscript    
  3. T subscript 1 end subscript less than T subscript 2 end subscript    
  4. T subscript 1 end subscript equals 2 text end text T subscript 2 end subscript    

The correct answer is: T subscript 1 end subscript less than T subscript 2 end subscript
