Question

The plot represents the flow of current through a wire at three different times.

The ratio of charges flowing through the wire at different times is

  1. 2 : 1 : 2    
  2. 1 : 3 : 3    
  3. 1 : 1 : 1    
  4. 2 : 3 : 4    

The correct answer is: 1 : 1 : 1


    ) 2 : 3 : 3
    Therefore, charge is equal to area under the curve.
    ∴ Ist rectangle =q=lb=2
    IInd rectangle =q=lb=2
    I I I r d blank t r i a n g l e equals q equals fraction numerator 1 over denominator 2 end fraction l b equals 2
    Hence, ratio is 1:1:1.
