Problem

The charge flowing through a conductor varies with time as shown in the graph. The graph consists of three segments:

OA

is a straight line from

(0,0)

(4\,\text{s}, 8\,\text{C})

AB

is a horizontal line from

4\,\text{s}

8\,\text{s}

, and

BC

is a straight line from

(8\,\text{s}, 8\,\text{C})

(12\,\text{s}, 0\,\text{C})

. Calculate the current in the conductor during the interval

t = 2\,\text{s}

t = 6\,\text{s}

, and

t = 10\,\text{s}
