A conductor carries a current that is decreasing exponentially with time. The current is modeled as I = I0e^(-t/τ), where I0 = 4.50 A is the current at time t = 0.00 s and τ = 0.50 s is the time constant. How much charge flows through the conductor between t = 0.00 s and t = 3.00 s?

The current through a conductor is modeled as $I(t)=I_{m} \sin (2 \pi[60 \mathrm{Hz}] t) .$ Write an equation for the charge as a function of time.

48. Charge Through Conductor The charge passing through a conductor increases over time as $q(t)=\left(1.6 \mathrm{C} / \mathrm{s}^{2}\right) t^{2}+(2.2 \mathrm{C} / \mathrm{s}) t$, where $t$ is in seconds. (a) What equation describes the current in the circuit as a function of time? (b) What is the current in the conductor at $t=0.0 \mathrm{~s}$ and at $t=2.0 \mathrm{~s}$ ?
