Question

current versus time graph shown here find the amount of charge that flows through the wire during this time period​

Answer 1

Current is defined as the instantaneous rate of flow of charges through a cross-sectional area of a conducting wire.

Mathematically , we can that :

$I = \dfrac{dq}{dt}$

$=>\displaystyle \int dq= \int I\: dt$

So we can say that area under the Current vs Time graph shall give us charge passing over a time interval.

Charge = Area under the graph

=> Charge = Area of Trapezium

=> Charge = ½ × (10+5) × 5

=> Charge = 37.5 C

So , final answer is 37.5 C.
