QUESTION FOUR (a) [8 marks]For a parallel connection of an imperfect coil (R = 500, L = 5mH) and a capacitor, C = 50pF, determine (i) A sketch of the circuit (ii) the circuit admittance (iii) the anti-resonance frequency (iv) the admittance at resonance (b) [15 marks]An ideal source has a peak-10-peak value of 20 volts and a variable frequency initially set at 1000 rad's. The source drives a series connection of a 80uF capacitor and 25mH inductor whose internal resistance is 42. Clearly showing your working, and indicating units appropriately, determine (i) and give a sketch of the time domain circuit, clearly labeling all components (ii) the sinusoidal expression for the source vollage (iii) the RMS value of the source voltage (iv) and sketch the phasor domain circuil, clearly labeling all components (v) the algebraic form of the driving point admittance (vi) the resonant frequency of the circuit, in Hz (vil) the Q-fator of the circuit (vii) the bandwidth of the circuit in Hz
