Question

For a cell, the graph between the p.d.(V) across the terminals of the cell and the current I drawn from the cell is shown in the fig. the emf and the internal resistance of the cell is E and r respectively.

  1. E equals 2 text end text V comma r equals 0.5 capital omega    
  2. E equals 2 text end text V comma r equals 0.4 capital omega    
  3. E greater than 2 V comma r equals 0.5 capital omega    
  4. E greater than 2 V comma r equals 0.4 capital omega    

The correct answer is: E equals 2 text end text V comma r equals 0.4 capital omega
