Question $10(1$ point$)$

$$

A series RC circuit consists of a $22$ F capacitor in series with a $330$ resistor across a pulsating dc source $($VS$)$ with a $90-$V peak $($Vpk$).$ VC $=56\mathrm{.}9$ V after one time constant. What is VC after an additional time constant?

Question $10$ options:

$79\mathrm{.}7$ V

$77\mathrm{.}9$ V

$56\mathrm{.}9$ V

$86\mathrm{.}5$ V
