QUESTION 2 (20 marks) (a) Under DC condition, find the voltage across the capacitor, Vc and current flowing (8) through the inductor, I in the circuit shown in Fig. 3. Find also the energy stored in the inductor and the capacitor. 3 A 292 www a 492 b 1+ Fig. 3 50 92 2F (b) The circuit shown in Fig. 4 is used in an audio receiver operating at an audio frequency range. 2 μF 592 i. Determine the total impedance of the circuit at an audio frequency of (5) 9.55 kHz. ii. If an AC voltage source v(t) = 100 cos (60000t +20°) is applied to ports ab, (5) find the steady state current (time domain) of the AC source. iii. Determine whether the current leads or lags the voltage v(t). Fig. 4 ell 10 mH iL 80 92 0.5 H 100 92 (2)
