Question: 838 A practical voltage source can be modeled using an ideal voltage source vSt = 120 cos2400t V in series with a 50- resistor. Convert

8–38 A practical voltage source can be modeled using an ideal voltage source vSðtÞ = 120 cosð2π400tÞ V in series with a 50-Ω

resistor. Convert the source into the phasor domain and then do a source transformation into a current source in parallel with an impedance. Finally, convert the current source back into the time domain.
