The current through an element is shown in the figure. Determine the total charge that pass through the element at a) t= 0s, b) t = 2s, c) t = 5s

Explanation

Rate of flow of charge is called current, `I=(aq)/(dt)`
Total charge pass through element, `dq=I, dt`
(a) At t = 0 s, I = 10 A
`dq=I dt=10xx0=0C`
(b) At t = 2 s, I = 5 A
`dq=I dt = 5xx2=10C`
(c ) At t = 5s, I = 0
`dq=Idt=0xx5=0 C`
