2. A resistive load (RL) is driven by a circuit comprising a sinusoidal voltage source (vs), a resistor (R), an inductor (L) and two capacitors (C1, C2), as shown in Figure 2. The sinusoidal voltage source provides the voltage vs(t) = Vo cos(at) (V. 5V, m = 1027 rad/s). The other devices have the following values: R=122, L =200 uH, C1 = 50 uF, C2 = 50 uF, RL = 20 w R W VS C1 C2 RL ell Figure 2 (a) Determine: (1) Which components are in parallel; (ii) Which components are in series; (iii) The natural frequency of the voltage source in Hz.
