At least one of the answers above is NOT correct. A $20\mu \mathrm{F}$ capacitor has an initial charge of $25\mu \mathrm{C}$. It is discharged through an $9000\Omega$ resistor. Find: a) the current at $20\mathrm{ms}$; $\mathrm{mA}$ b) the charge at $20\mathrm{ms}$; $\mu \mathrm{C}$ c) the power loss in the resistor at $20\mathrm{ms}$. $\mathrm{mW}$ d) How long does it take for the energy in the capacitor to drop to $20\%$ of its initial value? ms.
