The procedure is illustrated for the circuit in Fig. 8.5-2.
The first source function 200 sin314t is expressed as 200 cos(314t – 90°). Then, the
first source voltage phasor is 200e
–j90°
in the exponential form, 200∠–90° in the polar form
and 0 – j 200 in the rectangular form.
The second source function 250 sin(314t – 45°) is expressed as 250 cos(314t – 135°).
Then, the second source voltage phasor is 250e
–j135°
in the exponential form, 250∠–135° in
the polar form and –176.77– j176.77 in the rectangular form.
The value of
ω
314 rad/s. Therefore, the 4 mH inductor will have an impedance of
j1.256 Ω, the 5 mH inductor will have an impedance of j1.57 Ω
