Q 7.22 (c) Answer the following questions:
An applied voltage signal consists of a superposition of a voltage and an ac voltage of high frequency. The circuit consists of an inductor and a capacitor in series. Show that the dc signal will appear across and the ac signal across .
For a high frequency, the inductive reactance and capacitive reactance:
Hence the capacitor does not offer resistance to a higher frequency, so the ac voltage appears across L.
For DC, the inductive reactance and capacitive reactance:
Hence DC signal appears across Capacitor only.
