In this circuit, the sources have values

iS$1($t$)=16$ cos$(1000$ t$)$mA and

iS$2($t$)=18$ cos$(1000$ t $+0\mathrm{.}5)$mA$,$

while the components have values

C$=0\mathrm{.}2$F$,$ L$=1\mathrm{.}6$H$,$ and R$=1\mathrm{.}5$k$.$

Create a Th$$venin equivalent of the entire network external to the inductor L $($polarity as marked$),$ by determining:

$($a$)$ the Th$$venin voltage phasor VT

magnitude $=$ V

angle $=$ rad

$($b$)$ the Th$$venin impedance ZT

Re$\{$ZT$\}=$ k$$

Im$\{$ZT$\}=$ k$$
