Problem

The current in a wire varies with time according to

I(t)=4t\,\text{A}

, where

t

is in seconds, for

0\le t\le 5\,\text{s}

. What total charge passes a fixed point in the wire during this

5\,\text{s}

interval? a)

1.0\times10^{2}\,\text{C}

2.5\times10^{1}\,\text{C}

5.0\times10^{1}\,\text{C}

4.0\times10^{1}\,\text{C}
