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.
