Problem
A current flows through a resistor. The current is given by
I
(
t
)
=
(
10
−
2
t
)
A
I(t) = (10 - 2t)\,\text{A}
I
(
t
)
=
(
10
−
2
t
)
A
. Calculate the net charge that flows through the cross-section of the resistor from
t
=
0
s
t = 0\,\text{s}
t
=
0
s
to
t
=
8
s
t = 8\,\text{s}
t
=
8
s
. Note that the current direction reverses when
I
I
I
becomes negative.
