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

t=0 s
Total charge pass through element at t=0s is dq= ?
`I=(dq)/(dt)`
`dq=I.dt`
`dq=0`
t=2s
`I=(dq)/(dt) rArr dq= Idt`
Cureent through passing through element at time `t=2s I=5A`
`dq=5xx2=10C`
`dq=10C`.
`t=5s`
Current through passing at time t=5s
`I=0`
`I=(dq)/(dt) rArr dq= Idt=0xx5=0`
`dq=0`
