#### 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

) 2 : 3 : 3

Therefore, charge is equal to area under the curve.

∴ Ist rectangle =q=lb=2

IInd rectangle =q=lb=2

Hence, ratio is 1:1:1.

Therefore, charge is equal to area under the curve.

∴ Ist rectangle =q=lb=2

IInd rectangle =q=lb=2

Hence, ratio is 1:1:1.
