Answer to Question #58154 in Mechanical Engineering for Ryan

Question

The electric current i flowing in a device varies with time t. The equation linking the two variables is as follows.
i=2sin(5t)
The area under the graph represents the charge q that has passed over any given time interval.
Calculate the area and hence the charge by integrating the equation between t=t1 and t=t2
t1=0.4
t2=0.5
