Question

1. A wire has a current that varies in time as $\vec{I}(t) = I_0 \cos(\omega t) \hat{x}$, (1) where $I_0 = 2.2$ A and $\omega = 76$ rad/s. Graph the net charge that has passed a point in that wire as a function of time between $t = 0$ s and $t = 0.2$ s.

          1. A wire has a current that varies in time as
$\vec{I}(t) = I_0 \cos(\omega t) \hat{x}$,
(1)
where $I_0 = 2.2$ A and $\omega = 76$ rad/s. Graph the net charge that has passed a point in
that wire as a function of time between $t = 0$ s and $t = 0.2$ s.

1. A wire has a current that varies in time as
I⃗(t) = I0 cos(ω t) x̂,
(1)
where I0 = 2.2 A and ω = 76 rad/s. Graph the net charge that has passed a point in
that wire as a function of time between t = 0 s and t = 0.2 s.
