A $2\mathrm{.}00-$nF capacitor with an initial charge of $5\mathrm{.}06C$ is discharged through a $2\mathrm{.}61-k$ resistor.

$($a$)$ Calculate the current in the resistor $9\mathrm{.}00s$ after the resistor is connected across the terminals of the capacitor. $($Let the positive direction of the current be define such that $($:$\frac{dQ}{dt}>0.$
