Given the above circuit at steady state under a sinusoidal excitation where the current source is has frequency
\omega =400ra(d)/(s)
and phasor representation
(8)/(_(0))A
, find both the phasor and time-domain representations of: (a) the voltage across the source
(v)
, (b) the branch current
i_(2)
. (You may use
tan^(-1)((3)/(4))=36.87\deg =0.6435
radians.)
