Problem

In a laboratory experiment the current through a thin filament increases uniformly from

0

4.0\,\text{A}

over a time interval of

3.0\,\text{s}

. Assuming the current varies linearly with time, how much charge moves through the filament during this interval? (a)

12\,\text{C}

(b)

4.0\,\text{C}

(c)

6.0\,\text{C}

(d)

9.0\,\text{C}
